Meta React Specialization – Official Certification

This repository compiles my work, projects, and lessons learned during the Meta React Specialization on Coursera.
This is an internationally recognized certification that attests to a solid command of React.js, one of the most sought-after libraries in modern web development.

To pass the specialization, you must obtain at least 80% (8/10) in each course.
I have completed all modules with the highest grade.

Total duration: ~60 hours

• React Basics: ~30 hours
• Advanced React: ~30 hours
