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

Quick ES6 one liner:

const valuesArr = new Array("v1","v2","v3","v4","v5");   
const removeValFromIndex = new Array(0,2,4);

const arrayWithValuesRemoved = valuesArr.filter((value, i) => removeValFromIndex.includes(i))

Answer 2

I suggest you use Array.prototype.filter

var valuesArr = ["v1","v2","v3","v4","v5"];
var removeValFrom = [0, 2, 4];
valuesArr = valuesArr.filter(function(value, index) {
     return removeValFrom.indexOf(index) == -1;
})

Answer 3

filter + indexOf (IE9+):

function removeMany(array, indexes) {
  return array.filter(function(_, idx) {
    return indexes.indexOf(idx) === -1;
  });
}); 

Or with ES6 filter + find (Edge+):

function removeMany(array, indexes = []) {
  return array.filter((_, idx) => indexes.indexOf(idx) === -1)
}

Answer 4

Here's a quickie.

function removeFromArray(arr, toRemove){
    return arr.filter(item => toRemove.indexOf(item) === -1)
}

const arr1 = [1, 2, 3, 4, 5, 6, 7]
const arr2 = removeFromArray(arr1, [2, 4, 6]) // [1,3,5,7]
