What is ECMAScript?

• ECMAScript is a standardized scripting language that is used to define the specifications for the JavaScript language.

• ECMAScript is maintained by the Ecma International standards organization and is designed to be a stable and cross-platform scripting language that can be used for developing web applications and other software.

• The ECMAScript specification defines the syntax and semantics of the JavaScript language, as well as the core objects, functions, and features that are available to developers when working with JavaScript.

• The most widely used version of ECMAScript is ECMAScript 5 (ES5), which was released in 2009, and is supported by all modern web browsers. However, newer versions of ECMAScript, such as ECMAScript 6 (ES6) and ECMAScript 2021 (ES2021), have introduced new features and improvements to the language, such as arrow functions, template literals, and async/await syntax.

• One of the main goals of ECMAScript is to provide a standardized and interoperable scripting language that can be used across different platforms and environments.

• By defining a common language specification, ECMAScript helps to ensure that code written in JavaScript is portable and can be executed consistently across different browsers and platforms.

• Overall, ECMAScript is a key technology for developing web applications and other software using JavaScript, and its ongoing development and evolution are important factors in the continued growth and innovation of the JavaScript ecosystem.
