Higher-Order Functions in Java Script

 Higher-Order Functions in Java Script

Higher-order functions are functions that take other functions as arguments or return functions as their result. They are a powerful concept in functional programming and are widely used in JavaScript.

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

typescript

function multiplyByTwo(number) {

  return number * 2;

}

function apply(func, number) {

  return func(number);

}

console.log(apply(multiplyByTwo, 5)); // prints 10

The apply function takes another function as its first argument and applies it to the second argument.
