Full-Stack Web Applications

React.js is a JavaScript library for building fast, interactive, and reusable user interfaces. Developed by Meta (Facebook),
it follows a component-based architecture, making UI development modular and efficient. React uses a virtual DOM, which improves performance by updating only the necessary parts of the UI. It is widely used for single-page applications (SPAs), dashboards, and mobile apps (via React Native). With features like hooks, state management, and server-side rendering (Next.js), React is a top choice for modern web development.

AngularJS is a JavaScript framework developed by Google for building dynamic, single-page web applications (SPAs).
It uses a Model-View-Controller (MVC) architecture and two-way data binding, which allows real-time updates between the model and the view. AngularJS extends HTML with directives and makes web applications more interactive and responsive. Though it has been succeeded by Angular (TypeScript-based), many legacy applications still use it.
It is widely used for enterprise applications, dashboards, and dynamic web interfaces.

Django is a high-level Python web framework that simplifies web development by providing built-in tools for security,
scalability, and rapid development. It follows the Model-View-Template (MVT) architecture, making it easy to build dynamic and data-driven applications. Django includes features like authentication, ORM (Object-Relational Mapping), and an admin panel, reducing the need for third-party integrations. It is widely used for web applications, APIs, and content management systems (CMS) due to its robustness and flexibility.

A REST API (Representational State Transfer API) is a web service that allows communication between client and server
using HTTP methods It follows REST principles, making it scalable, stateless, and flexible for web applications.
Common HTTP methods include GET (fetch data), POST (create data), PUT (update data), and DELETE (remove data).
REST APIs return data in formats like JSON or XML, making them easy to integrate with front-end and mobile applications.
They are widely used for web services, microservices, and third-party integrations in modern web development.

AWS S3 (Simple Storage Service) is a scalable cloud storage service provided by Amazon Web Services (AWS).
It allows users to store, retrieve, and manage large amounts of data securely over the internet.
S3 provides features like versioning, encryption, and access control, making it ideal for backup, archiving, and web hosting.
Data in S3 is stored in buckets and can be accessed via REST APIs, SDKs, or AWS CLI.
It is widely used for data storage, machine learning workflows, and content distribution due to its durability and scalability.
