Objects — CRUD Operations & Dot vs Bracket Notation

An object is a collection of related data stored as key-value pairs. Keys are called properties. Values can be any data type — strings, numbers, booleans, arrays, functions, or even other objects.

1const person = {
2  name: "Arjun",      // string
3  age: 20,            // number
4  isStudent: true,    // boolean
5  scores: [85, 90],   // array
6  address: {          // nested object
7    city: "Mumbai",
8    pin: 400001
9  }
10};

Objects are used to model real-world entities and group related data and behaviour together.
