Understanding Arrow Functions, Callback Functions, and the Map Function in JavaScript
1. Arrow Functions:
- Arrow functions are a shorter way to write functions in JavaScript.
- They were introduced in ES6 and make the code cleaner and easier to read.
- It provides a shorter and more readable way to define functions, especially for anonymous functions or callbacks.
// Normal function
function add(a, b) {
return a + b;
}
// Arrow function
const addArrow = (a, b) => a + b;
console.log(add(2, 3)); // Output: 5
console.log(addArrow(2, 3)); // Output: 5
