OOPs stands for Object-Oriented Programming. It is a programming paradigm based on the concept of objects.
OOPs is based on the four main principles: Encapsulation, Inheritance, Polymorphism, and Abstraction.
Encapsulation is the process of hiding the implementation details from the user.
Inheritance is the process of creating new classes from existing classes.
Polymorphism is the ability of an object to take on many forms...
The main purposes of OOP are encapsulation, inheritance, and polymorphism.
Encapsulation helps to hide the complexity of the code and protect data from outside access.
Inheritance allows for the creation of new classes based on existing ones, reducing code duplication.
Polymorphism enables objects to take on multiple forms and behave differently depending on the context.
OOP promotes code reusability, modularity, and maint...
Pillars of OOPs are Abstraction, Encapsulation, Inheritance, and Polymorphism.
Abstraction: Hiding implementation details and showing only necessary information.
Encapsulation: Binding data and functions together to protect data from outside interference.
Inheritance: Creating new classes from existing ones, inheriting properties and methods.
Polymorphism: Ability of objects to take on multiple forms or behaviors.

Promises are objects representing the eventual completion or failure of an asynchronous operation.
Promises are used in JavaScript to handle asynchronous operations.
They can be in one of three states: pending, fulfilled, or rejected.
Promises can be chained together using .then() to handle success or failure.
They help avoid callback hell and make asynchronous code more readable.
Example: const myPromise = new Promise((res
