Joins are used to combine data from two or more tables based on a related column.
Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.
OOPs pillars are Abstraction, Encapsulation, Inheritance, and Polymorphism.
An array is a collection of elements of the same data type stored in contiguous memory locations.
Arrays can be one-dimensional or multi-dimensional
Elements in an array can be accessed using their index
Arrays can be initialized during declaration or later in the code
Arrays can be passed as arguments to functions
Common array operations include sorting and searching

Reactjs components are reusable, independent pieces of UI that can be composed together to build complex user interfaces.
Components are the building blocks of a React application
They can be class components or functional components

Java oops concepts include inheritance, encapsulation, polymorphism, and abstraction.
Inheritance allows a class to inherit properties and behavior from another class.
Encapsulation involves bundling data and methods that operate on the data into a single unit.
Polymorphism allows objects to be treated as instances of their parent class.
Abstraction hides the implementation details and only shows the necessary features to

Encapsulation and Inheritance are two important OOPS concepts.
Encapsulation: Bundling data and methods that operate on the data into a single unit. Example: Class with private data members and public methods.
Inheritance: Ability of a class to inherit properties and behavior from another class. Example: Subclass inheriting from a superclass.
Stack is a data structure that follows Last In First Out (LIFO) principle, while an array is a data structure that stores elements in contiguous memory locations.
Stack is dynamic in size, while array has a fixed size.
Stack operations include push and pop, while array operations include random access.
Example: Stack can be implemented using arrays, but arrays cannot be implemented using stacks.

OOPS (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
OOPS focuses on creating objects that interact with each other to solve complex problems
Key principles include encapsulation, inheritance, polymorphism, and abstraction
Encapsulation ensures that the internal state of an object is hidden from the outside world
Inheritance allows a class to inherit...

React lifecycle methods are special methods that are automatically called by React at specific points in a component's life cycle.
React components have several lifecycle methods such as componentDidMount, componentDidUpdate, componentWillUnmount, etc.
These methods allow developers to perform actions at specific points in a component's life cycle, such as fetching data, updating the UI, or cleaning up resources.
