Outline of the JavaScript programming language
High-level programming language
From Wikipedia, the free encyclopedia
The following outline is provided as an overview of and topical guide to JavaScript:
JavaScript (JS)[a] is a programming language and core technology of the Web, alongside HTML and CSS. It was created by Brendan Eich in 1995.[1] As of 2025, the overwhelming majority of websites (98.9%) uses JavaScript for client side webpage behavior.[2]
What type of language is JavaScript?
- Programming language — artificial language designed to communicate instructions to a machine, particularly a computer.
- High-level programming language — a programming language with strong abstraction from the details of the computer, such as having words, making it closer to natural language and easier to use than low level programming languages (which are much more cryptic).
- Compiled language — source code is converted ("compiled") to an intermediate form in order to be run.
- Interpreted language — bytecode is executed by a virtual machine, which performs just-in-time compilation.
- Dynamic programming language — allows various operations to be determined and executed at runtime, such as declaring data types, unlike in static languages, where the structure and types are fixed during compilation.
- Multi-paradigm programming language — A programming paradigm is a relatively high-level way to conceptualize and structure the implementation of a computer program. JavaScript supports many paradigms.
- Scripting language — programming language that is used for scripting, which is the act of writing a script, which is a relatively short and simple set of instructions which automate an otherwise manual process.
- Event-driven programming language — the flow of programs is determined by external events, such as inputs from mice, keyboards, touchpads and touchscreens, and external sensors.
- Imperative programming language — code directly controls execution flow and state change, explicit statements that change a program state
- Procedural programming language — organized as procedures that call each other
- Object-oriented programming language — organized as objects that contain both data structure and associated behavior, uses data structures consisting of data fields and methods together with their interactions (objects) to design programs
- Class-based programming language — supports object-oriented programming in which inheritance is achieved by defining classes of objects, versus the objects themselves
- Prototype-based programming language — includes object-oriented programming that avoids classes and implements inheritance via cloning of instances
- Declarative programming language — its code declares properties of the desired result, but not how to compute it, describes what computation should perform, without specifying detailed state changes
- Functional programming language — a desired result is declared as the value of a series of function evaluations, uses evaluation of mathematical functions and avoids state and mutable data
- Compiled language — source code is converted ("compiled") to an intermediate form in order to be run.
- High-level programming language — a programming language with strong abstraction from the details of the computer, such as having words, making it closer to natural language and easier to use than low level programming languages (which are much more cryptic).

Specifications of the language
- ECMAScript – this specification defines and standardizes the JavaScript language, such as its vernacular, syntax, and so on.
- ECMAScript version history
- Ecma International – the non-profit organization responsible for ECMAScript and many other communications standards.
Where JavaScript works (its runtime environments)
JavaScript works primarily in two main types of runtime environments:
- in web browsers, which power JavaScript from webpages using a JavaScript engine. This is referred to as being "client-side".[3]
- on Web servers, referred to as being "server-side"
Adaptive web design
JavaScript toolchain
Libraries
Package managers
Bundlers
Transpilers
Linters and formatters
