IDE (Integrated Development Environment):

An IDE is a software application that provides comprehensive tools and features to facilitate software development. It typically includes a code editor, debugger, build automation, and other productivity-enhancing features.

Inheritance:

Inheritance is a fundamental concept in object-oriented programming. It allows a class to inherit properties and behaviors from another class, promoting code reuse and creating hierarchical relationships between classes.

Interface:

An interface defines a contract for a class, specifying the methods that the class must implement. It enables loose coupling and helps achieve abstraction and polymorphism.

JavaScript:

JavaScript is a popular programming language used for building dynamic and interactive web applications. It runs on the client-side as well as the server-side.

Library:

A library is a collection of pre-written code that provides specific functionalities and can be reused across multiple projects. Libraries save development time and promote code reuse.

Machine Learning:

Machine learning is a field of artificial intelligence that focuses on developing algorithms and models that allow computers to learn and make predictions or decisions without explicit programming.

MVC (Model-View-Controller):

MVC is a software architectural pattern that separates the application logic into three interconnected components: the model (data), the view (user interface), and the controller (mediator between model and view). It enhances code organization and maintainability.

Object-Oriented Programming (OOP):

OOP is a programming paradigm that structures software around objects that encapsulate data and behaviors. It promotes code reusability, modularity, and abstraction.

Open Source:

Open source refers to software whose source code is freely available and can be modified and distributed by anyone. Open source software promotes collaboration, transparency, and community-driven development.

Performance Optimization:

Performance optimization involves improving the speed, efficiency, and resource usage of software applications. Techniques include code profiling, algorithmic improvements, caching, and resource management.

Platform:

A platform is a combination of hardware and software components that provide an environment for developing and executing software applications. Examples include operating systems, web platforms, and mobile platforms.

Refactoring:

Refactoring is the process of restructuring existing code to improve its design, readability, and maintainability without changing its external behavior. It helps eliminate technical debt and enhances code quality.

REST (Representational State Transfer):

REST is an architectural style for designing networked applications. It uses standard HTTP methods (GET, POST, PUT, DELETE) to manipulate resources and supports stateless, scalable, and loosely coupled interactions.
