// The default map in the Code Editor is a built-in ui.Map object called "Map".
// Let's refer to it as "defaultMap" for clarity.
var defaultMap = Map;
// ui.Map objects can be constructed. Here, a new map is declared.
var newMap = ui.Map({
center: {lat: 0, lon: 0, zoom: 1},
style: {position: 'bottom-right', width: '400px'}

// Add the newMap to the defaultMap;
defaultMap.add(newMap);
// Other UI widgets can be added to ui.Map objects, for example labels:
defaultMap.add(ui.Label('Default Map', {position: 'bottom-left'}));
newMap.add(ui.Label('New Map', {position: 'bottom-left'}));
// ...selectors:
defaultMap.add(ui.Select(['This', 'That', 'Other']));
// ...or buttons:
defaultMap.add(ui.Button('Click me'));
// You can also add ui.Map.Layer objects. Here, an ee.Geometry object
// is converted to a map layer and added to the default map.
