ECMAScript and JavaScript
ECMA
ECMA (European Computer Manufacturers Association) is an
international standards organization responsible for standardizing
ECMAScript, which serves as the foundation for JavaScript and other
scripting languages. This note provides a comprehensive overview of
ECMA, explains the difference between ECMAScript and JavaScript,
and highlights the main purpose of ECMA standards for JavaScript.
Founded in 1961, ECMA consists of member organizations
representing various industry sectors, including technology companies,
standards bodies, and government agencies.
The organization focuses on developing and maintaining standards to
promote interoperability and facilitate technological advancements.
ECMAScript vs. JavaScript:
ECMAScript:
ECMAScript refers to the standardized scripting language specification
governed by the ECMA organization.
It defines the syntax, semantics, and behavior of scripting languages,
including JavaScript.
It provides a common foundation for multiple implementations, ensuring
consistency and interoperability across platforms.

ECMAScript and JavaScript

ECMA

● ECMA (European Computer Manufacturers Association) is an international standards organization responsible for standardizing ECMAScript, which serves as the foundation for JavaScript and other scripting languages. This note provides a comprehensive overview of ECMA, explains the difference between ECMAScript and JavaScript, and highlights the main purpose of ECMA standards for JavaScript. ● Founded in 1961, ECMA consists of member organizations representing various industry sectors, including technology companies, standards bodies, and government agencies. ● The organization focuses on developing and maintaining standards to promote interoperability and facilitate technological advancements.

ECMAScript vs. JavaScript:

ECMAScript: ● ECMAScript refers to the standardized scripting language specification governed by the ECMA organization. ● It defines the syntax, semantics, and behavior of scripting languages, including JavaScript. ● It provides a common foundation for multiple implementations, ensuring consistency and interoperability across platforms. JavaScript:

● JavaScript is a popular programming language that serves as an implementation of the ECMAScript specification. ● It encompasses the ECMAScript rules, features, and core functionality, while also incorporating additional capabilities such as DOM manipulation, AJAX, and APIs specific to web browsers.

Purpose of ECMA Standards for JavaScript:

Interoperability ● The primary objective of ECMA standards for JavaScript is to promote interoperability across different implementations. ● By establishing a common set of rules and specifications, developers can write code that works consistently across various JavaScript engines, browsers, and platforms. Stability ● ECMA standards provide a stable foundation for the JavaScript language. They ensure that core language features, syntax, and semantics remain consistent over time, reducing compatibility issues and enabling long-term code maintenance. Language Evolution ● ECMA standards facilitate the evolution of the JavaScript language. Through a standardized process, proposals for new language features, enhancements, and modifications can be reviewed, refined, and incorporated into future ECMAScript versions. ● This enables JavaScript to stay relevant and adapt to the changing needs of the web development community. Collaboration and Consensus ● The ECMA standards process encourages collaboration among developers, implementers, and other stakeholders.
