Script Preparation code:
var arr1 = []; for(let i = 0; i < 10000; i++) { arr1.push(Math.floor(Math.random() * 5000)); } var arr2 = arr1.slice(0); arr2.sort((a, b) => a - b);
Tests:
Unsorted
var toSort = arr1.slice(0); toSort.sort((a, b) => a - b);
Sorted with check
var toSort = arr2.slice(0); let lastEntry; let isSorted = true; for(const entry of toSort) { if(lastEntry != null && entry < lastEntry) { isSorted = false; break; } lastEntry = entry; } if(!isSorted) { toSort.sort((a, b) => a - b); }
Sorted without check
var toSort = arr2.slice(0); toSort.sort((a, b) => a - b);
Unsorted with check
var toSort = arr1.slice(0); let lastEntry; let isSorted = true; for(const entry of toSort) { if(lastEntry != null && entry < lastEntry) { isSorted = false; break; } lastEntry = entry; } if(!isSorted) { toSort.sort((a, b) => a - b); }
