Sorts all key/value pairs contained in this object in place and returns undefined. The sort order is according to unicode code points 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).

const params = new URLSearchParams({ foo: '1', bar: '2' });
 
// Add a second foo parameter.
params.append("foo", 4);
 
params.toString();
// Returns "foo=1&bar=2&foo=4"
