React JS Full Course in Amharic | Lesson 3 – JSX Syntax Rules in React

እንኳን ወደ **React JS ሙሉ ኮርስ በአማርኛ** እንኳን በደህና መጣችሁ! 🚀

In **Lesson 3**, we unlock one of the most powerful parts of React — **JSX Syntax Rules** 🔥

If you’ve ever asked yourself:

* “JSX ምንድን ነው?”
* “HTML ነው ወይስ JavaScript?”
* “class ለምን className ይሆናል?”
* “object እና array እንዴት እንደሚ render ይደረጋል?”
* “Conditional rendering እንዴት እንጠቀማለን?”

👉 **This lesson answers all of that — step by step, clearly, in Amharic.**

We move from theory into **real JSX practice**, and by the end, JSX will feel natural — not confusing.
