delete values from array | not optimised - who cares

delete-values-from-array.js

var valuesToBeDeleted = [1, 5, 7, 15];
var mixedValues = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20];

// Boring solution:
valuesToBeDeleted.forEach(item => {
  var itemIndex = mixedValues.indexOf(item);
  mixedValues.splice(itemIndex, 1);
});

// Better solution: 
var cleanValues = mixedValues.filter(item => valuesToBeDeleted.indexOf(item) < 0);
