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.
