call() is used to invoke a function with a specified 'this' value and arguments provided individually.
bind() is used to create a new function with a specified 'this' value and initial arguments.
apply() is used to invoke a function with a specified 'this' value and arguments provided as an array.
Race condition is a situation where multiple threads/processes access and manipulate shared data simultaneously.
It can be eliminated by using synchronization techniques like locks, semaphores, and mutexes.
Another way is to use atomic operations that ensure the data is accessed and modified atomically.
Using thread-safe data structures can also prevent race conditions.
Example: Two threads trying to increment a shared var...

Software engineering principles are the best practices and guidelines for developing high-quality software.
Software should be designed with modularity and scalability in mind.
Code should be well-documented and easy to read.
Testing and debugging should be an integral part of the development process.
Version control should be used to manage code changes.
Security and privacy should be considered throughout the development
A Singleton class is a class that can only have one instance at a time.
It restricts the instantiation of a class to a single object.
It provides a global point of access to that instance.
It is often used in situations where a single object is required to coordinate actions across a system.
Example: Database connection manager, Configuration manager, Logger manager.
Testing principles ensure software quality, while design principles guide software development.
Testing principles include unit testing, integration testing, and acceptance testing.
Design principles include SOLID, DRY, and KISS.
Testing principles ensure that software meets requirements and is free of defects.
Design principles guide software development to be modular, maintainable, and scalable.

BFS (Breadth-First Search) is a graph traversal algorithm that explores all the vertices of a graph in breadth-first order.
BFS starts at a given vertex and explores all its neighbors before moving to the next level of vertices.
It uses a queue data structure to keep track of the vertices to be visited.
BFS guarantees that it visits all the vertices of a connected graph.
It can be used to find the shortest path between two

Object Oriented Programming is a programming paradigm that uses objects to represent real-world entities.
Encapsulation: bundling data and methods that operate on that data within one unit
Inheritance: creating new classes from existing ones, inheriting their properties and methods
Polymorphism: ability of objects to take on multiple forms or behaviors
Abstraction: hiding complex implementation details and providing a simp...
Abstraction is hiding implementation details while polymorphism is using a single interface for multiple types.
Abstraction: Encapsulation, Interfaces, Abstract classes
Polymorphism: Method Overloading, Method Overriding, Interfaces
Abstraction Example: Car - we don't need to know how the engine works to drive it
Polymorphism Example: Animal - different animals have different sounds but they all have a 'makeSound' method
