Remove multiple elements from array in Javascript/jQuery

Question

I have two arrays. The first array contains some values while the second array contains indices of the values which should be removed from the first array. For example:

<

Answer 1

Not in-place but can be done using grep and inArray functions of jQuery.

var arr = $.grep(valuesArr, function(n, i) {
    return $.inArray(i, removeValFromIndex) ==-1;
});

alert(arr);//arr contains V2, V4
