ES6 (ECMAScript 6)

ES6 (also known as ECMAScript 6) is the sixth major release of the ECMAScript language. It was released in June 2015 and brought significant changes and improvements to the JavaScript language. ES6 introduced many new features and syntax enhancements to make JavaScript more powerful, expressive, and easier to work with.

Some of the key features introduced in ES6 include:

1. let and const declarations for block-scoped variables.
2. Arrow functions for shorter and more concise function syntax.
3. Template literals for easier string interpolation.
4. Enhanced object literals to simplify object creation.
5. Default parameters for defining default values in function parameters.
6. Rest and spread operators to work with arrays and objects more easily.
7. Import and export statements for module support.
8. Classes and inheritance to create reusable object-oriented code.
9. Promises for handling asynchronous operations.
10. Generators for creating iterators.

These are just a few examples of the many features introduced in ES6. The adoption of ES6 has significantly improved the JavaScript development experience and made it easier to build complex and scalable web applications.
