Find next higher natural number that is divisble by another number

Write a function that takes two numbers, say x and y, as arguments. We need to check if x is divisible by y. If yes, then return x. If not, return the next higher natural number that is divisible by y.

const findDivisble = (x, y) => {
   if (x % y === 0) return x;

   if(y < 0) return 0;

   const divisor = parseInt(x / y);
   return divisor * y + y;
}

console.log(findDivisble(7, 3)); // 9
