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

Here's one possibility:

valuesArr = removeValFromIndex.reduceRight(function (arr, it) {
    arr.splice(it, 1);
    return arr;
}, valuesArr.sort(function (a, b) { return b - a }));
