difference between foreach loop and map

Comment

The main difference between forEach loop and map in JavaScript is that forEach is used to iterate and perform operations on each element of an array, while map is used to transform each element of an array into a new value and return a new array.

Example:
const numbers = [1, 2, 3, 4];

// forEach
numbers.forEach(function(num) {
  console.log(num * 2);
});
// Output: 2 4 6 8

// map
const doubledNumbers = numbers.map(function(num) {
  return num * 2;
});
console.log(doubledNumbers);
// Output: [2, 4, 6, 8]
