Javascript sort custom comparator function - sorting a sorted array

Question

I have an array of objects of the following form:

arr[0] = { \'item1\' : 1234, \'item2\' : \'a string\' };

I sort it first by \'item1\'

Answer 1

You can just import type-comparator with npm and then use queue to do the chaining:

const comparator = queue([
    map(x => x.item1, asc),
    map(x => x.item2, asc)
]);
arr.sort(comparator);
