Daily JavaScript Challenge: Determine if a Number is a Happy Number
Hey fellow developers! 👋 Welcome to today's JavaScript coding challenge. Let's keep those programming skills sharp!
The Challenge
Difficulty: Medium
Topic: Mathematical Operations
Description
Determine if a given positive integer is a 'Happy Number'. A happy number is defined by the following process: Starting with any positive integer, replace the number by the sum of the squares of its digits, and repeat the process until the number either equals 1 (where it will stay), or it loops endlessly in a cycle that does not include 1. Those numbers for which this process ends in 1 are happy numbers.
