JavaScript Objects

Object Definition

In JavaScript, objects are one of the most important data types. They are used to store collections of data in the form of key-value pairs. Objects in JavaScript are dynamic, meaning properties can be added or removed from them at any time.

let person = {
    name: 'John',
    age: 30,
    city: 'New York'
};
              

Object Methods:

You can also define functions as properties of an object:

let person = {
    name: 'John',
    greet: function() {
        console.log('Hello, my name is ' + this.name);
    }
};
