The sort() method sorts the elements of a typed array numerically in place and returns the typed array. This method has the same algorithm as Array.prototype.sort(), except that sorts the values numerically instead of as strings. TypedArray is one of the typed array types here.




compareFunction Optional
Specifies a function that defines the sort order.

Return value

The sorted typed array.


For more examples, see also the Array.prototype.sort() method.

let numbers = new Uint8Array([40, 1, 5, 200]);
// Uint8Array [ 1, 5, 40, 200 ] 
// Unlike plain Arrays, a compare function is not required
// to sort the numbers numerically.

// Regular Arrays require a compare function to sort numerically:
numbers = [40, 1, 5, 200];
// [1, 200, 40, 5]

numbers.sort((a, b) => a - b); // compare numbers
// [ 1, 5, 40, 200 ]
