// An ee.List object. var list = ee . List ([ 5 , 10 , 15 , 20 , 25 , 30 ]); // Fetch elements at specified 0-based positions in the list. print ( 'The second element' , list . get ( 1 )); print ( 'The fourth element' , list . get ( 3 )); print ( 'The last element' , list . get ( - 1 )); print ( 'The second to last element' , list . get ( - 2 )); // ee.Number and integer computed objects are valid inputs. print ( 'Computed object index input' , list . get ( list . get ( 0 ))); // The result of ee.List.get is an ambiguous object type. You need to cast the // result to the expected type to use it in subsequent instance methods. For // example, if you are fetching a number and wish to add it to another number, // you must cast the .get() result as an ee.Number. print ( 'Add fetched number to another number' , ee . Number ( list . get ( 1 )). add ( 2 ));
