What is encapsulation in JavaScript?

What is encapsulation in JavaScript?

Encapsulation in JavaScript is a programming concept that restricts access to certain components of an object, allowing for controlled interaction.

Can you give me an example of encapsulation?

Sure! In JavaScript, you can use closures to create private variables. For instance, you can define a function that returns an object with methods that access these private variables.

Why is encapsulation important?

Encapsulation is important because it helps to protect the internal state of an object, reduces complexity, and enhances code maintainability.

How does encapsulation differ from inheritance?

Encapsulation focuses on bundling data and methods that operate on that data, while inheritance allows one class to inherit properties and methods from another.
