The following outline is provided as an overview of and topical guide to JavaScript:

JavaScript (/ˈdʒɑːvəskrɪpt/), often abbreviated as JS, is a programming language and core technology of the Web, alongside HTML and CSS. 99% of websites use JavaScript on the client side for webpage behavior.[1]

What type of thing is JavaScript?

edit
 
Screenshot of JavaScript code

JavaScript is an example of all of the following:

  • Programming language – formal computer language designed for writing programs to run on computers. JavaScript is mostly used for automating web pages, or making programs that work within web pages. Its capabilities include producing graphics, and manipulating text, HTML code, as well as CSS rules and elements.
    • High-level programming language – programming language more like human language and less tedious than machine code, providing features that standardize common tasks, permit rich debugging, and maintain machine independence. Rather than dealing with registers and memory addresses, JavaScript features variables, functions, and other abstract constructs, which makes it slower than machine code but much easier to write.
      • Dynamic programming language – class of high-level programming languages which execute certain programming behaviors as they run, making them more flexible than static programming languages (which perform those behaviors during compilation). For example, as with most scripting languages, JavaScript is dynamically typed: its types are associated with each value, rather than just with each expression. (E.g., a variable that is at one time bound to a number may later be re-bound to a string.[2]).
      • Interpreted language – programming language for writing instructions that are executed directly by an interpreter, without compiling. This is what makes JavaScript programs platform independent; they are typically interpreted by the various JavaScript engines embedded in browsers.
      • Multi-paradigm programming language – programming language designed to allow programmers to use the most suitable programming style and associated language constructs for a given job, considering that no single paradigm solves all problems in the easiest or most efficient way. See Programming styles supported.
      • Object-based language – programming language that uses the idea of encapsulating state and operations inside "objects". Object-based languages need not support inheritance or subtyping, but those that do are also said to be "object-oriented", and include those which support a prototype-based programming style, like JavaScript, which do not have classes, but in which objects instead inherit their code and data directly from other "template" objects.
      • Scripting language – programming language that supports scripts. Scripts automate the execution of tasks that could alternatively be executed one-by-one by a human operator. Scripts are programs written for a special run-time environment; the main type of run-time environment that JavaScript programs are written for are browsers.
      • Untyped programming language – an untyped language, such as JavaScript, allows any operation to be performed on any data, which are generally considered to be sequences of bits of various lengths.[3]

Names of JavaScript

edit

Etymology of JavaScript

edit
  • Etymology of JavaScript – the language was initially named Mocha, then changed to LiveScript, then renamed to JavaScript.
  • "Java" – the "Java" in "JavaScript" has caused confusion, implying a relation with the Java programming language. JavaScript is not a version, distribution, or spin-off of Java, though JavaScript did take inspiration from Java for its syntax. Netscape's naming JavaScript after Java has been characterized as a marketing ploy to take advantage of the popularity of the word "Java" at the time.
  • "Script" – the "Script" in "JavaScript" no longer describes the language accurately. While JavaScript started out as a scripting language, it has developed into a sophisticated multi-paradigmatic programming language, though it retains its scripting language functionality.

Synonyms of JavaScript

edit
  • ECMAScript – the specification language upon which JavaScript is based. The terms EMCAScript and JavaScript are used interchangeably within the field. 'ES' has also been used as a prefix for shorthand names of versions of JavaScript: [4]
    • 'ES5': ECMAScript Fifth Edition, adopted in 2009.
    • 'ES6' / 'ES2015': ECMAScript Sixth Edition, adopted in 2015.
    • 'ES7' / 'ES2016': ECMAScript Seventh Edition, adopted in 2016.
    • 'ES2017': ECMAScript Eighth Edition, adopted in 2017.
    • 'ES2018': ECMAScript 2018 – 9th Edition
    • 'ES2019': ECMAScript 2019 – 10th Edition
    • 'ES2020': ECMAScript 2020 – 11th Edition
    • 'ES2021': ECMAScript 2021 – 12th Edition
    • 'ES2022': ECMAScript 2022 – 13th Edition
    • 'ES2023': ECMAScript 2023 – 14th Edition
  • JScript – essentially, "JavaScript for Internet Explorer". Microsoft reverse engineered JavaScript and then named the implementation JScript to avoid infringing upon Sun's ownership of the JavaScript trademark. Since then, Microsoft has switched over to using the name JavaScript to refer to the implementation of JScript used in its Edge browser.
  • Vanilla JavaScript or "Vanilla JS" – jargon for "plain JavaScript", that is, JavaScript not extended by any frameworks or additional libraries.

JavaScript trademark

edit
  • Ownership of the JavaScript trademark – "JavaScript" as a trademark is technically owned by Oracle, which acquired Sun, which acquired NetScape, which created JavaScript and initially registered the trademark.
  • Non-enforcement of the JavaScript trademark – the trademark doesn't appear to be enforced, and may be indefensible. Many companies and individuals throughout the field are using it in their product names as a generic term, apparently without legal repercussions.

Uses of JavaScript

edit

JavaScript can be used for:

Prerequisites for using JavaScript

edit

Equipment required for using JavaScript

edit
  • Computer – JavaScript is a programming language, so, of course you need a computer to use it
  • Web browser – scripts written in JavaScript reside on most webpages, which require a web browser to access. Most web browsers have a JavaScript engine built-in that run webpage scripts.

Prerequisites to understanding JavaScript

edit

Prerequisites to understanding JavaScript – JavaScript is one of the three core technologies used for defining webpages. JavaScript is a complementary technology that works with HTML and CSS, amongst others. JavaScrpt refers to and modifies the markup, and therefore understanding these other languages is useful for writing JavaScript programs.

  • HTML (HyperText Markup Language) – standard markup language used to create the web pages (HTML files) that make up the World Wide Web and which are read and presented by web browsers. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. HTML elements form the building blocks of HTML files ("HTML pages"), and JavaScript is used to dynamically change HTML pages by modifying their HTML elements or creating new ones.
  • CSS (Cascading Style Sheets) – style sheet language used for describing the presentation of a document written in a markup language (including HTML).[5] CSS is designed primarily to enable the separation of document content from document presentation, including aspects such as the layout, colors, and fonts.[6] This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple HTML pages to share formatting by specifying the relevant CSS in a separate .css file, and reduce complexity and repetition in the structural content. JavaScript can dynamically modify CSS to change the presentation of web pages.

Tools required for JavaScript programming

edit

Tools required for JavaScript programming – the only tool required for writing programs in JavaScript is a text editor, though other tools are very useful.

  • Text editor – program used for editing plain text files. JavaScript programs can be written in even the simplest text editor.
  • (For optional but useful tools, see JavaScript tools, below)

Method of execution

edit

Method of execution – how a computer program is started. Typically, JavaScript programs are embedded within the HTML markup of a webpage, or called from within the HTML markup using a script call, and are executed automatically by the browser when it reads the webpage. Another method is the bookmarklet, which requires the user to click on it to execute. Various methods of execution for JavaScript programs include:

  • Methods of executing scripts in web browsers:
    • Embedding in webpage HTML
      • Script tags – a script is embedded in a webpage by including it between <script> and </script>
      • Script call
      • Bookmarklet – technique of saving JavaScript within a bookmark or hyperlink, so that it can be executed by clicking on it. In many cases, the bookmarklet can be dragged and dropped to the browser toolbar for easier access. Here is an example bookmarklet:
        • JavaScript:name=prompt("What is your name?"); alert("Hello, " + name);
    • Installed as a browser extension – a browser extension is a plug-in that extends the functionality of a web browser in some way. Many browser extensions are written in JavaScript.
      • Installed as an add-on in Firefox – Firefox add-ons allow the user to add or augment application features, use themes to their liking, and handle new types of content. Many add-ons are written in JavaScript.
    • Installed as a userscript – JavaScript program written to modify web pages to augment browsing. They are installed in browsers by use of a userscript manager browser extension like Tampermonkey or Greasemonkey. A userscript feature is also available for registered users of Wikipedia, and can augment editing and viewing of that encyclopedia's pages.
    • As a bookmark – using the bookmarklet technique.
  • Methods of executing scripts in runtime environments:
  • Methods of executing scripts in other programs:

JavaScript system requirements

edit

Environment support for JavaScript

edit

Environment support for JavaScript – where JavaScript can be run. This includes client-side support in browsers, server-side support in web servers, and runtime environments to provide support in operating systems on desktop computers and other machines.

  • On the World Wide Web – JavaScript may be executed at the web server (or "server-side") upon webpages (or to generate them) before they are sent to the client (the user's browser), or executed client-side by the client upon receipt of a webpage. Client-side JavaScript is typically embedded in the HTML of webpages.
    • Client-side environment support – this is achieved through client-side scripting. Client-side scripts are supported in:
      • Browsers – JavaScript can run in browsers that include a JavaScript engine (see below). JavaScript sourcecode that is embedded in a webpage's HTML is executed by the JavaScript engine in the browser automatically when the browser reads the page.
    • Server-side environment support – this is implemented through server-side scripting. Server-side scripts are supported in:
  • Local environment support – JavaScript can be used to write applications for use on end user computers, and those applications can be run using a JavaScript runtime environment, such as Node.js.
JavaScript engines
edit

JavaScript engine  (list) – program or library which executes JavaScript code. A JavaScript engine may be a traditional interpreter, or it may utilize just-in-time compilation to bytecode in some manner.[7] A JavaScript engine is most commonly included in web browsers, but is also a key component of JavaScript runtime environments and other software (such as database management systems).

  • Chakra – JavaScript engine developed by Microsoft for its Microsoft Edge web browser. It is a fork of the JScript engine used in Internet Explorer.
  • SquirrelFish – bytecode interpreter rewritten from JavaScriptCore.
  • Nashorn – JavaScript engine developed in the Java programming language by Oracle. It is based on the Da Vinci Machine (JSR 292) and was released with Java 8. Its purposes are to enable embedding JavaScript in Java applications, and to develop standalone JavaScript applications.
  • Rhino – JavaScript engine written fully in Java and managed by the Mozilla Foundation as open source software. It is intended to be used in server-side applications, hence there is no built-in support for the Web browser objects that are commonly associated with JavaScript.
  • SpiderMonkey – the JavaScript engine in Firefox
  • Tamarin – still supported as part of Flash Player.
  • V8 – used in Google Chrome, Couchbase Server, MongoDB, and Node.js
  • Comparison of JavaScript engines
  • (For engines no longer actively developed or maintained, see Outmoded JavaScript engines)
JavaScript runtime environments
edit

JavaScript runtime environments

  • Node.js – open-source, cross-platform JavaScript runtime environment for executing JavaScript code server-side, to produce dynamic web page content before the page is sent to the user's web browser. Node.js is built upon the Chrome V8 JavaScript engine.
  • Seed – interpreter and a library of the GNOME project to create standalone applications in JavaScript. It uses the JavaScript engine JavaScriptCore of the WebKit project.
  • Comparison of server-side JavaScript solutions
Other JavaScript-based solutions
edit
  • CouchDB – server database that uses JavaScript as its query language.

Features of JavaScript

edit
  • Universal web support – all modern Web browsers support JavaScript with a built-in JavaScript engine.

JavaScript specifications and standards

edit
  • Main specifications
    • ECMAScript – standard specification originally based on JavaScript. Since ECMAScript's inception, JavaScript has followed that specification. While JavaScript aims to be compatible with ECMAScript, it also provides additional features not described in the ECMA specifications.[8]
    • CommonJS – project to create specifications for JavaScript beyond client-side scripting, to expand it into a more full-fledged language. For example, for writing server-side scripts and native desktop applications.
  • Asynchronous module definition (AMD) – API specification for JavaScript that defines code modules and their dependencies, and loads them asynchronously if desired.
  • Content Security Policy – computer security standard introduced to prevent cross-site scripting (XSS), clickjacking and other code injection attacks resulting from execution of malicious content in the trusted web page context.
  • JSGI – interface between web servers and JavaScript-based web applications and frameworks.

Programming styles supported

edit

JavaScript supports the following programming paradigms:

Components of the JavaScript language

edit

JavaScript syntax

edit

JavaScript syntax (see tutorial) – set of rules that define correct structure for lines of code in a JavaScript program, such as when semicolons are needed at the end of a statement, whether or not letter case matters, where and how to use parentheses, what words are reserved as part of the language, the use of white space, the proper format for variable declarations, expressions, statements, functions, and so on.

Data types in JavaScript

edit

[[Data type (JavaScript)|Data types in JavaScript] – a type is a classification of data which defines the operations that can be done on the data, the meaning of the data, and the way values of that type can be stored.

Variables in JavaScript

edit

Variables in JavaScript[12] – a variable is a storage location paired with an associated symbolic name (an identifier), which contains some known or unknown quantity of information referred to as a value. They correspond to variables in mathematics, but aren't limited to representing just numbers.

Operators in JavaScript

edit

Operators in JavaScript[13] – an operator is

Expressions in JavaScript

edit

Expressions in JavaScript – an expression is

Statements in JavaScript

edit

Statements in JavaScript[14] – a statement is the smallest standalone element in a programming language that expresses some action to be carried out. Statements are instructions that command the computer to perform a specified action.

Functions in JavaScript

edit

Functions in JavaScript[2] – in JavaScript, subroutines are called "functions". A subroutine is a sequence of program instructions that perform a specific task, packaged as a unit. This unit can then be used (and reused) in the program wherever that particular task needs to be performed.

Classes in JavaScript

DOM manipulation in JavaScript

edit
  • DOM – this stands for Document Object Model, the hierarchy (tree) produced by the browser of all the elements of a webpage. By processing the DOM via "methods" (functions stored as object properties, that is, the actions that can be performed on objects), JavaScript can dynamically change the page's HTML[18], such as:

Server-side scripting features

JavaScript approaches

edit
  • Ajax "(asynchronous JavaScript and XML)" – set of web development techniques using many web technologies on the client-side to create asynchronous Web applications. With Ajax, web applications can send data to and retrieve from a server asynchronously (in the background) without interfering with the display and behavior of the existing page. By decoupling the data interchange layer from the presentation layer, Ajax allows for web pages, and by extension web applications, to change content dynamically without the need to reload the entire page.
  • Dynamic HTML – predecessor of Unobtrusive JavaScript.
  • JavaScript templating –
  • JSONP –
  • Remote scripting –
  • Unobtrusive JavaScript –

JavaScript programming techniques

edit
  • Bookmarklet – technique of saving JavaScript within a bookmark or hyperlink, so that it can be executed by clicking on it. In many cases, the link can be dragged and dropped to the browser toolbar for easier access.
  • HTML scripting – how locally executable scripts (such as those written in JavaScript) may be used in a web page.
