users.sort((a, b) => a.firstname.localeCompare(b.firstname))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]

var points = [40, 100, 1, 5, 25, 10];

const unsorted = ['d', 'd', 'h', 'r', 'v', 'z', 'f', 'c', 'g'];
const sorted = unsorted.sort();

//["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]sort function explained javascript
