How to divide an unknown integer into a given number of even parts using Javascript

Question

I need help with the ability to divide an unknown integer into a given number of even parts — or at least as even as they can be. The sum of the parts should be the original

Answer 1

You may get maximum integer coefficient as x/y rounded down to integer and remainder with x%y. Than simply break remainder into 1's and add those 1's to corresponding number of items:

const breakIntoParts = (num, parts) => 
        [...Array(parts)].map((_,i) => 
          0|(i < num%parts ? num/parts+1 : num/parts))

console.log(JSON.stringify(breakIntoParts(20, 6)));
