Day - 26

Hello, everyone. I am going to share something with you. Are you ready to read this article? Then, let's go!

1. Problem 2634. Filter Elements from Array

/*
 * @param {number[]} arr
 * @param {Function} fn
 * @return {number[]}
 */	

var filter = function (arr, fn) {
  let res = [];
  for (let i = 0; i < arr.length; i++) {
    if (fn(arr[i], i)) {
      res.push(arr[i]);
    }
  }
  return res;
};        

2. Problem 2635. Apply Transform Over Each Element in Array

/*
 * @param {number[]} arr
 * @param {Function} fn
 * @return {number[]}
 *	

var map = function (arr, fn) {
  let returnedArr = [];
  for (let i = 0; i < arr.length; i++) {
    returnedArr[i] = fn(arr[i], i);
  }
  return returnedArr;
};        

That's all I want to share with you! Thanks for your attention.
