Learning Outcomes of the Counter App

Conclusion of the Counter App

Learning Outcome

By completing this project, you have learned how to build a simple web application using React from the ground up. You have:

  • Set up a React development environment (Node.js, Create React App).
  • Created React components and used the useState hook to manage dynamic data.
  • Handled user events with onClick and updated the UI in real time.
  • Organized the project files (src and public folders) and understood the directory structure.
  • Pushed code to GitHub and deployed the app live on Netlify.

These skills are fundamental for any React developer. The Counter App is a basic example, but the concepts carry over to larger projects (state management, props, component structure, etc.).
