React questions, answered
Do I need to know JavaScript before learning React?
Yes, a working grasp of JavaScript helps a lot. Learnr can build you a JavaScript course first if you want the foundation.
Is React hard to learn?
The core ideas are small and consistent. Once components and state make sense, most of React builds on those same patterns.
