Introduction:
Web development relies on two key components: the frontend (what users see) and the backend (what powers it behind the scenes). Understanding their roles is essential to any successful web project.

• What is the frontend?
  It’s the user-facing part of the website or app. It includes design, layout, and interactivity.
  Common tools: HTML, CSS, JavaScript, React, Vue.js.

• What is the backend?
  It handles the logic, database management, and server-side operations.
  Common tools: Node.js, PHP, Python, Ruby, Laravel, Django, SQL.

• How they work together:
  The frontend communicates with the backend via APIs to fetch or send data.

• Best practices:

  • Frontend: mobile-first design, accessibility, performance optimization.

  • Backend: security, automated testing, clean architecture, scalability.

Conclusion:
A strong application comes from a well-balanced and well-integrated backend and frontend. Each plays a crucial role in the user experience.
