The ECMAScript 2027 Language Specification is the official standard document that defines the JavaScript programming language. Maintained by TC39, it provides the normative rules, algorithms, and semantics that JavaScript engines must follow. It serves as the authoritative reference for browser vendors, runtime implementers, and developers seeking to understand the precise behavior of the language.

It is built as an open-source project for javascript engine developers. ECMAScript® 2027 Language Specification is free to use. ECMAScript® 2027 Language Specification is available on the web and the command line.
It is developed by TC39 (Spain), and the product first shipped in 2027. Key capabilities include Language Specification, Standard Compliance, and Multipaged View.
