TypedArray.prototype.sort()

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 it sorts the values numerically instead of as strings by default. TypedArray is one of the typed array types here.

Try it

Syntax

sort()
sort(compareFn)

Parameters

compareFunction Optional

A function that defines the sort order. The return value should be a number whose positivity indicates the relative order of the two elements. The function is called with the following arguments:

a

The first element for comparison. Will never be undefined.

b

The second element for comparison. Will never be undefined.

If omitted, the array elements are converted to strings, then sorted according to each character's Unicode code point value.

Return value

The sorted typed array.

Examples

Using sort

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

let numbers = new Uint8Array([40, 1, 5, 200]);
numbers.sort();
// 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];
numbers.sort();
// [1, 200, 40, 5]

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