Encapsulation is the process of hiding internal details and providing a public interface for accessing and manipulating data.
Encapsulation bundles data and methods together into a single unit.
It helps in achieving data abstraction and data hiding.
By encapsulating data, we can control access to it and prevent unauthorized modifications.
Encapsulation promotes code reusability and maintainability.
Example: A class in objec...
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.

Abstraction is the process of simplifying complex systems by focusing on essential details.
Abstraction involves hiding unnecessary details and exposing only relevant information.
It allows developers to create models or representations that capture the essential aspects of a system.
Abstraction helps in managing complexity, improving code reusability, and enhancing maintainability.

Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.
Polymorphism is a fundamental concept in object-oriented programming.
It enables code reusability and flexibility.
Polymorphism can be achieved through method overriding and method overloading.
Example: A parent class Animal can have multiple child classes like Dog, Cat, and Bird. They can ...

String is immutable, while StringBuilder is mutable and more efficient for concatenating strings.
String is immutable, meaning once created, its value cannot be changed. StringBuilder is mutable, allowing for modifications without creating new objects.
String concatenation creates a new string object each time, while StringBuilder modifies the existing object directly.
StringBuilder is more efficient for concatenating mul...
Async and await are keywords in JavaScript used to work with asynchronous code.
Async is used to define a function as asynchronous, allowing it to run in the background without blocking the main thread.
Await is used to pause the execution of an async function until a Promise is settled, and then resumes the function with the resolved value.
Async/await is a more readable and cleaner way to write asynchronous code compare...
