The most accurate and up-to-date ECMAScript specification. It contains the content of the most recent yearly snapshot plus any finished proposals (those that have reached Stage 4 in the proposal process and thus are implemented in several implementations and will be in the next practical revision) since that snapshot was taken. This Ecma Standard defines the ECMAScript 2022 Language. It is the twelfth edition of the ECMAScript Language Specification. Since publication of the first edition in 1997, ECMAScript has grown to be one of the world's most widely used general-purpose programming languages. It is best known as the language embedded in web browsers but has also been widely adopted for server and embedded applications. ECMAScript is based on several originating technologies, the most well-known being JavaScript (Netscape) and JScript (Microsoft). The language was invented by Brendan Eich at Netscape and first appeared in that company's Navigator 2.0 browser.
Features
- ECMAScript is an object-oriented programming language for performing computations and manipulating computational objects within a host environment
- This Standard defines the ECMAScript 2022 general-purpose programming language
- ECMAScript as defined here is not intended to be computationally self-sufficient
- ECMAScript was originally designed to be used as a scripting language, but has become widely used as a general-purpose programming language
- It provides a host environment of objects and facilities, which completes the capabilities of the scripting language
- Intended for use by both professional and non-professional programmers
