JavaScript nested destructuring

Comment

// Destructuring an object > array > object structure
const returnedObject = {
  docsArray: [
    {socketRoom: '', routes: []},
    {socketRoom: '', routes: []},
    {socketRoom: '', routes: []},
  ]
}

// this will destructure the first and second elements from docsArray, and spread the remainder
const {docsArray: [element0, element1, ...remainder]} = returnedObject

// taking this further with destructing properties from element0 
const {docsArray: [{socketRoom0, routes0} = element0, {socketRoom1, routes1} = element1]} = returnedObject

// note the syntax for destructing Objects and Arrays
const {propName} = Object
const [element0, element1] = Array

// then one layer deep where Object[propName] is an Array
const {propName: [element0]} = Object

// then two layers, where element0 is an Object
const {propName: [{propName} = element0]}

// three layers
const {propName: [{propName: [element00]} = element0]}

nested array destructuring javascript

Comment

// destructuring array & nested array & combine array into single array
let person = ["John", "Sandy", "Sam", ["Mike", "Max"], "Diego", "Paul"];
// empty comma is like skipping array index. I skipped "Sam"
const [a, b, , c, ...d] = person;

let friend = [d, "Tom", "Jerry"] 
let newFriend = [...d, "Tom", "Jerry"]

console.log(a); // output: "John"
console.log(b); // output: "Sandy"
console.log(c); // output: [ "Mike", "Max" ]
console.log(d); // output: ["Diego", "Paul"]
console.log(friend); // output: [ [ 'Diego', 'Paul' ], 'Tom', 'Jerry' ]
console.log(newFriend); // output: [ 'Diego', 'Paul', 'Tom', 'Jerry' ]
