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:
let users = {
'boys': ['boy1', 'boy2', 'boy3'],
'girls': ['girl1', 'girl2', 'girl3'],
};
Let's output some element from this object:
console.log(users['boys'][1]); // will output 'boy2'
Given the following object with students:
let students = {
'group1': ['name11', 'name12', 'name13'],
'group2': ['name21', 'name22', 'name23'],
'group3': ['name31', 'name32', 'name33'],
};
Display the first student from the third group.
