Quick sort VS. Selection sort

Globals

• const data = [ ...new Array(250).fill(0).map(Math.random) ]

• 0 ops/s

  function quickSort(arr, left, right) { const len = arr.length; let pivot; let partitionIndex; if (left < right) { pivot = right; partitionIndex = partition(arr, pivot, left, right); quickSort(arr, left, partitionIndex - 1); quickSort(arr, partitionIndex + 1, right); } return arr; } function partition(arr, pivot, left, right) { const pivotValue = arr[pivot]; let partitionIndex = left; for (var i = left; i < right; i++) { if (arr[i] < pivotValue) { swap(arr, i, partitionIndex); partitionIndex++; } } swap(arr, right, partitionIndex); return partitionIndex; } function swap(arr, i, j) { const temp = arr[i]; arr[i] = arr[j]; arr[j] = temp; } quickSort(data);
• 0 ops/s

  function selectionSort(arr) { const len = arr.length; let minIdx; let temp; for (let i = 0; i < len; i++) { minIdx = i; for (let j = i + 1; j < len; j++) { if (arr[j] < arr[minIdx]) { minIdx = j; } } temp = arr[i]; arr[i] = arr[minIdx]; arr[minIdx] = temp; } return arr; } selectionSort(data);
