sort array in ascending order javascript

By default, the sort method sorts elements alphabetically. To sort numerically just add a new method which handles numeric sorts (sortNumber, shown below) -

var numArray = [140000, 104, 99];
numArray.sort(function(a, b) {
  return a - b;
});

console.log(numArray);

Documentation:

Mozilla Array.prototype.sort() recommends this compare function for arrays that don't contain Infinity or NaN. (Because Infinity - Infinity is NaN, not 0).

Also examples of sorting objects by key.

how does array.sort((a, b) => {return a - b};) order an array of integers in ascending order instead of returning the result of (a-b) and storing it into the array?

Here's a basic sort function: function bubbleSort (array, callback) { let length = array.length; while (length > 0) { for (let i = 0; i < length - 2; i++) { const current = i; const next = i + 1; if (callback(array[current], array[next]) > 0) { [array[current], array[next]] = [array[next], array[current]]; } } length--; } return array; } Similar to JS's sort function, it takes a callback function which receives two elements from the array and returns a number. If the returned number is larger than zero, the elements are swapped. So if we were to sort an array like this: ['A', 'N', 'C'] With a function like this: function (a, b) { if (a < b) { return -1; } else { return 1; } } It will compare each letter (the < and > operators can be used to compare strings: 'Aardvark' < 'Anteater' === true), and sort them in ascending order. ['A', 'C', 'N'] More on reddit.com
