Javascript loop an array to find numbers divisible by 3

Question

I am needing to find the correct way to have javascript loop through an array, find all numbers that are divisible by 3, and push those numbers into a new array.

Here is

Answer 1

console.log([1, 2, 3, 4, 5, 6, 7].filter(function(a){return a%3===0;}));

Array.filter() iterates over array and move current object to another array if callback returns true. In this case I have written a callback which returns true if it is divisible by three so only those items will be added to different array

Answer 2

Using Filter like suggested by Nina is defiantly the better way to do this. However Im assuming you are a beginner and may not understand callbacks yet, In this case this function will work:

function loveTheThrees(collection){
        var newArray = []
        for (var i =0; i< collection.length;i++){
            if (myArray[i] % 3 === 0){
                newArray.push(collection[i])
            }
        }
        return newArray;
    }
