JavaScript Object Programming Examples

Last Updated : 14 Jul, 2023

JavaScript Object is the collection of properties and the property is in key, value pair format. These objects are quite different from JavaScript’s primitive data types (Number, String, Boolean, null, undefined, and symbol) in the sense that these primitive data types all store a single value each (depending on their types).

Syntax:

let obj = {
    key1: value1,
    key2: value2,
    ...
};

Example: Here is the basic example of a Javascript Object.

JavaScript

let obj = { 
    firstName: "Hello", 
    lastName: "Geeks"
} 
  
console.log(obj.firstName + " " + obj.lastName); 

Output

Hello Geeks
