Outline of the JavaScript programming language
high-level programming language
The following outline is provided as an overview of and topical guide to JavaScript:
JavaScript (JS) is a programming language and core technology of the Web, alongside HTML and CSS. Created by Brendan Eich in 1995, it is maintained by Ecma International's TC39 technical committee, with related Web APIs maintained by W3C and WHATWG. As of 2025, JavaScript is the most widely used programming language on GitHub. However, TypeScript, which is a version of JavaScript that is strict about types and is statically typed, overtook JavaScript on GitHub by August 2025.
What type of language is JavaScript?
Programming language – artificial language designed to communicate instructions to a machine, more so 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 representation 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 compiling.
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.
The public source identifies “Outline of the JavaScript programming language” as high-level programming language. This brief keeps that definition visible, then builds a research path around Outline, JavaScript and programming.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Outline of the JavaScript programming language”, the useful work is to connect “high-level programming language” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 11, 2026. The linked authority identifier is Q136702559. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1995 and 2025.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
