Web Development
Process of creating and maintaining websites and web applications.
Broadly categorized into two main areas: front-end development and back-end development.
Frontend
This involves everything that users interact with directly in their web browsers.
Key aspects include:
- HTML: The structure of web pages.
- CSS: The styling and layout of web pages.
- JavaScript: Adding interactivity and dynamic behavior to web pages.
Sample Frameworks and Libraries: React, Angular, or Vue.js that streamline development.
Backend
Runs the core functionality, business logic, data processing, database interactions.
