nested array destructuring javascript

1// destructuring array & nested array & combine array into single array
2let person = ["John", "Sandy", "Sam", ["Mike", "Max"], "Diego", "Paul"];
3// empty comma is like skipping array index. I skipped "Sam"
4const [a, b, , c, ...d] = person;
5
6let friend = [d, "Tom", "Jerry"] 
7let newFriend = [...d, "Tom", "Jerry"]
8
9console.log(a); // output: "John"
10console.log(b); // output: "Sandy"
11console.log(c); // output: [ "Mike", "Max" ]
12console.log(d); // output: ["Diego", "Paul"]
13console.log(friend); // output: [ [ 'Diego', 'Paul' ], 'Tom', 'Jerry' ]
14console.log(newFriend); // output: [ 'Diego', 'Paul', 'Tom', 'Jerry' ]
