What are Objects?


An object in JavaScript is a way to store related data together in a single structure. Instead of keeping many separate variables, objects group everything in one place.

For example, information about a user such as name, age, and city can all be stored inside one object. This makes programs more organized and easier to understand.

Objects are used everywhere in real-world applications — from user profiles and product details to settings and API data.

Why Objects Are Important

  • They group related data together
  • They make programs easier to manage 
  • They help represent real-world things  
  • They store both data and functions 
  • They are used in almost every application  

Without objects, managing complex data would be very difficult.

Here, each piece of information is stored in a separate variable. As the data grows, managing these variables becomes confusing.

This is why objects are used to group related information.

Now, all related data is stored inside a single object called user.

This makes the code cleaner and easier to manage.

This example shows two ways to access object properties — dot notation and bracket notation.

By understanding objects, students gain the ability to organize data properly and build structured, professional JavaScript applications.
