Functional Programming in Java Script

 Functional Programming in Java Script

Functional programming is a programming paradigm that emphasizes the use of functions to create reusable code. In JavaScript, functional programming is supported through features like anonymous functions, higher-order functions, and closures.

Here's an example of a higher-order function that takes a function as an argument:

php

Copy code

function applyOperation(num, operation) {

  return operation(num);

}

function double(num) {

  return num * 2;

}

var result = applyOperation(5, double); // returns 10
