Learn Javascript | Codewars 7 kyu Season 2 - Last Digits of a Number

Welcome back to another exciting Codewars Kata run through! In today's video, we'll be solving a JavaScript challenge that requires us to implement a function called lastDigit which returns the last D digits of an integer N as a list. ? Problem Statement: Our job is to implement a function which returns the last D digits of an integer N as a list. ? Special cases: If D is greater than (the number of digits of N), return all the digits. If D is less than or equal to 0, return an empty list. ? Examples: N = 1, D = 1, result = [1] N = 1234, D = 2, result = [3, 4] N = 637547, D = 6, result = [6, 3, 7, 5, 4, 7] ? Solution: In this video, we'll walk you through a concise and elegant solution in JavaScript: We're going to convert the integer n to a string and then use the spread operator to create an array of its digits. Use the map() function to convert each digit back to a number. Use the splice() function to extract the last d digits from the array. ?
