ECMAScript is a standardized scripting language specification that defines the core functionality of JavaScript and similar languages. Developed by Ecma International, it serves as the foundation for web scripting and is widely used in browsers, Node.js, and other environments. The standard ensures compatibility and consistency across different implementations, allowing developers to write portable code.

The first version of ECMAScript, known as ECMAScript 1 (ES1), was published in 1997 as a formalization of JavaScript, originally created by Netscape. Subsequent versions, including ECMAScript 2 (ES2) in 1998 and ECMAScript 3 (ES3) in 1999, introduced minor refinements and bug fixes. However, significant advancements came with ECMAScript 5 (ES5), released in 2009, which added features like strict mode, JSON support, and improved error handling.

ECMAScript 6 (ES6), published in 2015, marked a major evolution with features such as classes, modules, arrow functions, promises, and template literals. This version greatly enhanced developer productivity and readability. Subsequent updates, including ECMAScript 2016, 2017, 2018, 2019, 2020, 2021, and 2022, introduced incremental improvements like async/await, optional chaining, and nullish coalescing.

The ECMAScript standard is maintained by Ecma International, a non-profit organization that collaborates with industry stakeholders to evolve the language. New features are proposed through a formal process involving public discussion, testing, and voting. Implementations like V8 (used in Chrome and Node.js), SpiderMonkey (Mozilla), and JavaScriptCore (Safari) ensure broad compatibility with the standard.

ECMAScript remains a critical component of modern web development, enabling dynamic, interactive applications while maintaining interoperability across platforms. Its ongoing evolution continues to address emerging needs in programming and web technologies.
