js bubble sort

// Bubble sort is a sorting algorithm that sorts data in an array by looping through the array
// and checking if the current item is greater than the next item.
// It will continue to loop through, swapping the items until they are sorted.
// If no swaps are made during a pass, then the data is sorted and we break the loop.

const bubbleSort = (arr) => {
  // This variable is used to either continue or stop the loop
  let continueSorting = true;

  // while continueSorting is true
  while (continueSorting) {
    // Here we are setting continueSorting to false. Because below we check to see if a swap is made,
    // if a swap is made, then we continue sorting. If no swaps were made, then were are done sorting,
    // and stop our while loop.
    continueSorting = false

    // loop through the arr from 0 to next to last
    for(let i = 0; i < arr.length - 1; i++) {
      // check if we need to swap
      if(arr[i] > arr[i + 1]) {
        // swap
        let temp = arr[i];
        arr[i] = arr[i + 1];
        arr[i + 1] = temp;

        // since a swap was made, we want to continue sorting
        continueSorting = true;
      }

  // After all swaps have been made, then we return our sorted array

Bubble Sort Javascript

/*A slightly better solution involves tracking a variable called "checked" 
which is initially set to FALSE and becomes true when there is a swap during the iteration. 
Running this code on a do while loop to run the sorting function only when "checked" is true 
ensures that the function will not run on a sorted array more than once.*/
