what is the algorithm for javascript array.sort
function bubbleSort(arr){ var len = arr.length; for (var i = len-1; i>=0; i--){ for(var j = 1; j<=i; j++){ if(arr[j-1]>arr[j]){ var temp = arr[j-1]; arr[j-1] = arr[j]; arr[j] = temp; } } } return arr; } bubbleSort([7,5,2,4,3,9]); //[2, 3, 4, 5, 7, 9] bubbleSort([9,7,5,4,3,1]); //[1, 3, 4, 5, 7, 9] bubbleSort([1,2,3,4,5,6]); //[1, 2, 3, 4, 5, 6]
how the sort function works javascript
const unsorted = ['d', 'd', 'h', 'r', 'v', 'z', 'f', 'c', 'g']; const sorted = unsorted.sort(); console.log(sorted); //["c", "d", "d", "f", "g", "h", "r", "v", "z"] const unsortedNums = [45, 56, 3, 3, 4, 6, 7, 45, 1]; const sortedNums = unsortedNums.sort((a, b) => { return a - b; }); console.log(sortedNums); //[1, 3, 3, 4, 6, 7, 45, 45, 56]
