making a function that pulls all number from an array divisible by 3

Question

var array = [3, 4, 6, 5, 9, 10, 21];

var divThree = [];

var loveTheThrees = function (array) {
  for (i = 0; i = array.length; i++) {
    if (array[i] % 3 === 0) {
      amount.push(divThree[i]);
    }
  }
}

I am just learning Javascript and having a bit of trouble with this function. I can feel im close but cant figure out what im doing wrong.

Answer 1

Just use filter()

divThree = array.filter(x => x%3 === 0);
