js bubblesort code example

Example 1: javascript bubble sort

const bubbleSort = (arr) => {
  for (let i = 0; i < arr.length; i++) {
    for (let j = 0; j < arr.length - i; j++) {
      if (arr[j] > arr[j + 1]) {
        let tmp = arr[j];
        arr[j] = arr[j + 1];
        arr[j + 1] = tmp;
      }
    }
  }
  return arr;
}

Example 2: javascript bubble sort

const bubbleSort = array => {
  const arr = Array.from(array); // avoid side effects
  for (let i = 1; i < arr.length; i++) {
    for (let j = 0; j < arr.length - i; j++) { // starts up to length - 1
      if (arr[j] > arr[j + 1]) {
        [arr[j], arr[j + 1]] = [arr[j + 1], arr[j]];
      }
    }
  }
  return arr;
};

console.log(bubbleSort([4, 9, 2, 1, 5]));

Example 3: boble sorting javascript

function bubbleSort(array) {
	for (let i = 0; i < array.length; i++) {
		for (let j = 0; j < array.length; j++) {
			let item = array[j];

			var nextItem = array[j + 1];
			if (item > nextItem) {
				array[j] = nextItem;
				array[j + 1] = item;
			}
		}
	}
	return array;
}

console.log(bubbleSort([9, 5, 7, 1, 0, 2, 4, 10, 1, 6, 3, 5, 8]));
console.log(bubbleSort([900, 5, 70, 0.1, 0, 02, 4, 100, 1, 6, 35, 56, 8]));

Example 4: how to do bubble sort in javascript

function BubbleSort(arr) {
      const sortedArray = Array.from(arr);
      let swap;
      do {
        swap = false;
        for (let i = 1; i < sortedArray.length; ++i) {
          if (sortedArray[i - 1] > sortedArray[i]) {
            [sortedArray[i], sortedArray[i - 1]] = [sortedArray[i - 1], sortedArray[i]];
            swap = true;
          }
        }
      } while (swap)
      return sortedArray;
    }

    console.log(BubbleSort([7,99,1,88,34,2,90,7]));

Example 5: javascript bubleshort example

// like using Array.reverse();
function bubbleReverse(arr) {
    for (let i = arr.length - 1; i > 0; i--) {
        for (let j = arr.length - 1; j > 0; j--) {
            if (arr[j] > arr[j - 1]) {
                let temp = arr[j];
                arr[j] = arr[j - 1];
                arr[j - 1] = temp;
            }
        }
    }
    return arr;
}

// like using Array.sort();
function bubbleSort(arr) {
    for (let i = 0; i < arr.length - 1; i++) {
        for (let j = 0; j < arr.length - 1; j++) {
            if (arr[j] > arr[j + 1]) {
                let temp = arr[j];
                arr[j] = arr[j + 1];
                arr[j + 1] = temp;
            }
        }
    }
    return arr;
}

Example 6: buble sort in js

let bubbleSort = (inputArr) => {    let len = inputArr.length;    for (let i = 0; i < len; i++) {        for (let j = 0; j < len; j++) {            if (inputArr[j] > inputArr[j + 1]) {                let tmp = inputArr[j];                inputArr[j] = inputArr[j + 1];                inputArr[j + 1] = tmp;            }        }    }    return inputArr;};
