Lets understand JavaScript vs ECMAScript what are the differences

JavaScript and ECMAScript are closely related, but they serve different purposes. ECMAScript is the standardized scripting language specification defined by ECMA International, while JavaScript is the widely used implementation of that specification. Essentially, ECMAScript provides the guidelines, and JavaScript brings them to life in browsers and various environments. ECMAScript establishes the core functionalities and syntax rules that JavaScript follows. Each version of ECMAScript introduces new features and improvements, which JavaScript engines incorporate over time. For example, ECMAScript 6 (ES6) brought major enhancements like let and const for variable declarations, arrow functions, and modules, which significantly improved JavaScript’s usability and efficiency. JavaScript, on the other hand, includes additional capabilities beyond ECMAScript, such as APIs for web development—DOM manipulation, event handling, and browser-specific features. JavaScript engines, such as Google’s V8 (used in Chrome and Node.js), interpret and execute JavaScript code based on ECMAScript specifications, but also add optimizations and extra functionalities suited for different platforms. In summary, ECMAScript defines the foundational rules, while JavaScript extends them with practical tools for web development. JavaScript evolves with ECMAScript updates, but it remains the go-to language for interactive and dynamic web experiences. Understanding their relationship helps developers make informed decisions about coding practices and staying up to date with new advancements.
