=== Java ===
A common misconception is that JavaScript is directly related to [[Java (programming language)|Java]].<!-- While one is intentionally similar to the other, they're different. (Previously the misconception sentence said "JavaScript is similar to Java" but that's not a misconception) --> Both indeed have a C-like syntax (the C language being their most immediate common ancestor language). They are also typically [[Sandbox (computer security)|sandboxed]], and JavaScript was designed with Java's syntax and standard library in mind. In particular, all Java keywords were reserved in original JavaScript, JavaScript's standard library follows Java's naming conventions, and JavaScript's {{code|lang=javascript|code=Math}} and {{code|lang=javascript|code=Date}} objects are based on classes from Java 1.0.<ref name="popularity">{{cite web | url=https://brendaneich.com/2008/04/popularity/ | title=Popularity | first=Brendan | last=Eich | author-link=Brendan Eich | date=April 3, 2008 | access-date=January 19, 2012 | archive-date=July 3, 2011 | archive-url=https://web.archive.org/web/20110703020955/https://brendaneich.com/2008/04/popularity/ | url-status=live }}</ref>

Both languages first appeared in 1995, but Java was developed by [[James Gosling]] of Sun Microsystems and JavaScript by [[Brendan Eich]] of Netscape Communications.

The differences between the two languages are more prominent than their similarities. Java has [[static typing]], while JavaScript's typing is [[Dynamic typing|dynamic]]. Java is loaded from [[Compiler|compiled]] bytecode, while JavaScript is loaded as human-readable source code. Java's objects are [[Class-based programming|class-based]], while JavaScript's are [[Prototype-based programming|prototype-based]]. Finally, Java did not support functional programming until Java 8, while JavaScript has done so from the beginning, being influenced by [[Scheme (programming language)|Scheme]].

=== JSON ===
[[JSON]] is a data format derived from JavaScript; hence the name JavaScript Object Notation. It is a widely used format supported by many other programming languages.

=== Transpilers ===
Many websites are JavaScript-heavy, so [[transpiler]]s have been created to convert code written in other languages, which can aid the development process.<ref name="transpilers">{{cite web |title=List of languages that compile to JS |first=Jeremy |last=Ashkenas |website=[[GitHub]] |author-link=Jeremy Ashkenas |url=https://github.com/jashkenas/coffeescript/wiki/List-of-languages-that-compile-to-JS |access-date=February 6, 2020 |archive-date=January 31, 2020 |archive-url=https://web.archive.org/web/20200131233044/https://github.com/jashkenas/coffeescript/wiki/List-of-languages-that-compile-to-JS |url-status=live }}</ref>

[[TypeScript]] and [[CoffeeScript]] are two notable languages that transpile to JavaScript.

=== WebAssembly ===
[[WebAssembly]] is a newer language with a [[bytecode]] format designed to complement JavaScript, especially the performance-critical portions of [[web page]] scripts. All of the major [[JavaScript engine]]s support WebAssembly,<ref>{{cite web|url=https://visualstudiomagazine.com/articles/2017/11/06/edge-webassembly.aspx|title=Edge Browser Switches WebAssembly to 'On' -- Visual Studio Magazine|website=Visual Studio Magazine|access-date=2018-02-09|archive-date=2018-02-10|archive-url=https://web.archive.org/web/20180210002432/https://visualstudiomagazine.com/articles/2017/11/06/edge-webassembly.aspx|url-status=live}}</ref> which runs in the same [[Sandbox (computer security)|sandbox]] as regular JavaScript code.

[[asm.js]] is a subset of JavaScript that served as the forerunner of WebAssembly.<ref>{{cite web | url=https://asmjs.org/faq.html | title=frequently asked questions | publisher=asm.js | access-date=April 13, 2014 | archive-date=June 4, 2014 | archive-url=https://web.archive.org/web/20140604012024/https://asmjs.org/faq.html | url-status=live }}</ref>
