ES6
ES6 (ECMAScript 2015) is a major update to the JavaScript language specification that introduced significant new syntax and features to enhance code readability, maintainability, and functionality. It includes additions such as arrow functions, classes, template literals, destructuring, and modules, which modernize JavaScript development. This version marked a pivotal shift in the language, making it more powerful and suitable for large-scale applications.
Developers should learn ES6 syntax because it is now the standard for modern JavaScript development, widely supported in browsers and Node.js, and essential for writing cleaner, more efficient code. It is particularly useful for building complex web applications, improving code organization with modules and classes, and leveraging features like promises for better asynchronous programming. Knowledge of ES6 is often a prerequisite for working with modern frameworks like React, Vue, or Angular.
