• Virtual DOM: React uses a virtual representation of the DOM to optimize rendering, improving performance by min...read more

Oops concepts are fundamental principles of object-oriented programming that help in designing and implementing software solutions.

• Encapsulation: Bundling data and methods that operate on the data into a single unit (class).

• Inheritance: Allowing a class to inherit properties and behavior from another class.

• Polymorphism: Ability to present the same interface for different data types.

• Abstraction: Hiding the complex ...read more
