Javascript - sort array based on another array

Question

Is it possible to sort and rearrange an array that looks like this:

itemsArray = [ 
    [\'Anne\', \'a\'],
    [\'Bob\', \'b\'],
    [\'Henry\', \'b\'],
             


        

Answer 1

this is probably too late but, you could also use some modified version of the code below in ES6 style. This code is for arrays like:

var arrayToBeSorted = [1,2,3,4,5];
var arrayWithReferenceOrder = [3,5,8,9];

The actual operation :

arrayToBeSorted = arrayWithReferenceOrder.filter(v => arrayToBeSorted.includes(v));

The actual operation in ES5 :

arrayToBeSorted = arrayWithReferenceOrder.filter(function(v) {
    return arrayToBeSorted.includes(v);
});

Should result in arrayToBeSorted = [3,5]

Does not destroy the reference array.
