Web development is the process of creating, building, and maintaining websites and web applications. It is generally divided into three main areas: Front-end (the visual interface users interact with), Back-end (the server-side logic, databases, and infrastructure), and Full-stack (handling both). [1, 2]
The Three Core Technologies
Every web developer starts by mastering the foundation of the internet: [1, 2, 3]
- HTML (HyperText Markup Language): Structures the content of a web page.
- CSS (Cascading Style Sheets): Controls the design, layout, and responsiveness of the page.
- JavaScript: Adds dynamic functionality, logic, and interactivity. [1, 2, 3, 4]

Expanding Your Skillset
To build modern, professional web applications, developers usually move beyond the basics and learn frameworks and libraries: [1]
- Front-end Frameworks: React, Angular, or Vue.
- Back-end Languages & Frameworks: Node.js, Python (Django/Flask), or PHP.
- Database Systems: MongoDB, PostgreSQL, or MySQL. [1, 2, 3, 4, 5]
Essential Tools
Modern web developers rely on a standard set of tools to streamline their workflow: [1]
- Code Editor: Visual Studio Code is the industry-standard, free code editor.
- Version Control: Git and GitHub track changes and allow teams to collaborate. [1, 2, 3, 4, 5]
If you are looking to learn web development from scratch, you can explore structured, high-quality learning paths on MDN Web Docs or Codecademy. [1, 2]
