URLSearchParams: sort() method

The URLSearchParams.sort() method sorts all key/value pairs contained in this object in place and returns undefined. Key/value pairs are sorted by the values of the UTF-16 code units of the keys. This method uses a stable sorting algorithm (i.e., the relative order between key/value pairs with equal keys will be preserved).

Syntax

sort()

Parameters

None.

Return value

None (undefined).

Examples

// Create a test URLSearchParams object
const searchParams = new URLSearchParams("c=4&a=2&b=3&a=1");

// Sort the key/value pairs
searchParams.sort();

// Display the sorted query string
console.log(searchParams.toString());

The result is:

a=2&a=1&b=3&c=4
