Filtering an array from another array in vue

This might be something really simple, but I just can’t figure it out. What I’m trying to do is take 2 arrays and filter out what I don’t need and only
return the one array.

So what I have right now is this

let array1 = [1, 2, 3];
let array2 = [1, 2, 3, 4, 5, 6];

and what I would like is to return array 2 with only the items that doesn’t show up in array1 so that would be 4, 5,6.

This is what I have so far

return array1.forEach(a => {
    array2.filter(aa => aa !== a)
});

and that doesn’t return anything

>Solution :

let array1 = [1, 2, 3];
let array2 = [1, 2, 3, 4, 5, 6];

let array3 = array2.filter(i => !array1.includes(i));

console.log(array3)
