Multidimensional Structures in JavaScript

You can combine multidimensional arrays and objects to create various structures. Let's, for example, create an object containing arrays inside it:

javascriptlet users = {
  'boys':  ['boy1', 'boy2', 'boy3'],
  'girls': ['girl1', 'girl2', 'girl3'],
};

Let's output some element from this object:

javascriptconsole.log(users['boys'][1]); // will output 'boy2'

javascriptlet students = {
  'group1': ['name11', 'name12', 'name13'],
  'group2': ['name21', 'name22', 'name23'],
  'group3': ['name31', 'name32', 'name33'],
};
