Returns the value at the specified key in the current collection

public function get(
  Tk $k,
): ?Tv;

If the key is not present, null is returned. If you would rather have an exception thrown when a key is not present, then use at().


  • Tk $k - the key from which to retrieve the value.


  • ?Tv - The value at the specified key; or null if the key does not exist.
