Ten days of JS is a collection of 10 problems that can be done in any order. Problems range from easy to medium. You can find all the solutions by clicking on Repl.it - I added comments directly in the solution when I thought it was necessary.
Write a function to determine if a number is "happy".
A happy number is a number 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 equals 1 (where it will stay), or it loops endlessly in a cycle which does not include 1. Those numbers for which this process ends in 1 are happy numbers.
