What are the differences between ES5 and ES6 (ECMAScript 2015)?
- Arrow functions
- Block-scoped variables (let, const)
- Classes
- Promises
ES5 and ES6 (ECMAScript 2015) are two versions of JavaScript with notable differences. ES6 introduced arrow functions, which provide a concise syntax for writing functions. Block-scoped variables (let, const) were also introduced in ES6, offering better control over variable scoping. Classes were introduced in ES6 to provide a cleaner syntax for defining object blueprints. Promises were introduced to handle asynchronous operations more effectively, aiding in writing asynchronous code that is easier to read and maintain.
