## <a id="section_m3p_myb_5db"></a>Description

Returns a list of all keys from a given map of key/value pairs. If the given map is null, `getKeys` returns an empty list.

Alternatively, you can use the [keys ( )](/wcp_docs/yig1648434013350.html) function, which returns a set that contains the map keys. If you need to use a list, you can convert the returned set to a list. Example: `[].addAll(map.keys())`
