`list.map(callback[, thisArg])`

Loops through the values of the list, calling callback for each one until the list ends. The return values of callback are used to populate the returned list.

]);
var names = todos.map(function(todo){
  return todo.name;
});
names //-> DefineList["dishes","lawn"]

The return value of callback, including undefined values are used to populated the resulting list.
thisArg {Object}:
