ES6 also known as ECMAScript 2015 is a major JavaScript update released on 17 June 2015. Despite being released quite a few years back, it remains a very important step in the development of JavaScript as a programming language that took over the world.

ES6 introduces many new features and improvements to JavaScript, including classes, modules, arrow functions, and enhanced object literals, that can make it easier and more efficient to write and maintain code.

If you’re new to JavaScript or just getting started with ES6, here are some key concepts and features that appeared in ES6:

  • Classes: ES6 introduces a class syntax that allows you to define “blueprints” for objects in a more concise and object-oriented way. Classes can have constructors, methods, and static methods, and they can be extended and inherited from.
  • Modules: ES6 introduces a module system that allows you to split your code into separate files and import and export functions and variables between them. Modules make it easier to organize and reuse your code, and they can help you avoid naming conflicts and global variables.
  • Arrow functions: Arrow functions are a new syntax for defining functions in JavaScript that are shorter and more concise than regular functions. They do not have their own this value, which can make them easier to work with in certain situations.
  • Enhanced object literals: ES6 introduces several improvements to object literals, including the ability to use computed property names and shorthand syntax for defining methods and properties.
