What are some key features introduced in ECMAScript 6 (ES6) and later versions of JavaScript?



ECMAScript 6 (ES6), released in 2015, introduced several significant features and improvements to JavaScript. Since then, subsequent versions of ECMAScript, including ES7, ES8, ES9, ES10, ES11, ES12, and ES2022, have also brought new functionalities and enhancements. Here are some key features introduced in ES6 and later versions of JavaScript: 1. Block-Scoped Variables (let and const): ES6 introduced the `let` and `const` keywords for declaring variables. Unlike the `var` keyword, which has function scope, `let` and `const` have block scope, meaning they are limited to the block in which they are defined. `let` allows variable reassignment, while `const` declares constants that cannot be reassigned. 2. Arrow Functions: Arrow functions provide a concise syntax for defining functions. They have a shorter syntax than regular functions and automatically bind the `this` value lexically, avoiding the need for explicit binding. Arrow functions are especially useful for writing inline functions or callbacks. 3. Enhanced Object Literals: ES6 introduced enhancements to object literals, making them more expressive and flexible. Object literals can now have computed property names, shorthand syntax for methods ....
