Javascript filter array by data from another

Question

I have an array object:

[
    { id:1, name: \'Pedro\'},
    { id:2, name: \'Miko\'},
    { id:3, name: \'Bear\'},
    { id:4, name: \'Teddy\'},
    { id:5, n         


        

Answer 1

Or if you are using jQuery, another option may be:

var arr1 = [1, 3, 5],
    arr2 = [{ id: 1, name: 'Pedro' },
    { id: 2, name: 'Miko' },
    { id: 3, name: 'Bear' },
    { id: 4, name: 'Teddy' },
    { id: 5, name: 'Mouse' }],
    filtered = $.grep(arr2, function (item) {
    if (arr1.indexOf(item.id) > -1) {
        return true;
    }
});
