ECMAScript

ECMAScript is a standardized scripting language that forms the foundation of JavaScript, enabling developers to write consistent code across different browsers and environments. It defines the core features, syntax, and behavior of the language, ensuring interoperability and predictability. Over time, ECMAScript has evolved with new versions adding features like arrow functions, classes, and async programming, making JavaScript more powerful and easier to use. Think of it as the official blueprint or language specification that guides how JavaScript is created and implemented.
