Benchmark: toLowerCase() Sorting

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

function makeid(length) {
    let result = '';
    const characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
    const charactersLength = characters.length;
    let counter = 0;
    while (counter < length) {
      result += characters.charAt(Math.floor(Math.random() * charactersLength));
      counter += 1;
    }

    return result;
}

var arr = [];
for(var i = 0; i < 100000; i++){
  arr.push({value:makeid(5)});
}

Tests:

Convert During Sort
arr.sort((l, r) => { const a = l.value.toLowerCase(); const b = r.value.toLowerCase(); if (a < b) { return -1; } else if (b > a) { return 1; } else { return 0; } });
Map Before Sort
arr.map(x => x.value.toLowerCase()).sort((a,b) => { if (a < b) { return -1; } else if (b > a) { return 1; } else { return 0; } });
lodash sortBy()
_.sortBy(arr, (x) => x.value.toLowerCase());
localeCompare()
arr.sort((a, b) => a.value.localeCompare(b.value));
