ECMAScript is commonly used for client-side scripting on the World Wide Web, and it is increasingly being used for server-side applications and services using runtime environments such as Node.js, [3] deno [4] and bun.
With server-side rendering, static HTML can be sent from the server to the client, and client-side JavaScript then makes the web page dynamic by attaching event handlers to the HTML elements in a process called hydration. Examples of frameworks that support server-side rendering are Next.js, Nuxt.js, Angular, and React.
An ECMAScript engine is a software platform that can run code written in ECMAScript, a programming language more commonly known as JavaScript. More formally, an ECMAScript engine is, at least in part, a "conforming implementation" of the ECMAScript programming language specified by the ECMA-262 international standard.

Emscripten is an LLVM/Clang-based compiler that compiles C and C++ source code to WebAssembly, [4] primarily for execution in web browsers. Emscripten allows applications and libraries written in C or C++ to be compiled ahead of time and run efficiently in web browsers, typically at speeds comparable to or faster than interpreted or dynamically ...
The proposed fourth edition of ECMA-262 (ECMAScript 4 or ES4) would have been the first major update to ECMAScript since the third edition was published in 1999. The specification (along with a reference implementation) was originally targeted for completion by October 2008. [ 15 ]
A JavaScript engine is a software component that executes JavaScript code. The first JavaScript engines were mere interpreters, but all relevant modern engines use just-in-time compilation for improved performance. [1] JavaScript engines are typically developed by web browser vendors, and every major browser has one.
It contains an allocator and garbage collector (GC) for ArkTS/JS objects, a standard library that conforms to the ECMAScript specification, an interpreter for running the ARK Bytecode (abc) generated by ARK front-end components, an inline cache for acceleration, a statically typed compiler, a C++/C function interface for Native API (NAPI ...
