Understanding JSX in React
When starting with React, many beginners get confused by JSX. But don't worry, I'm here to help you along the way!
๐ก What is JSX? JSX is a syntax that looks like HTML but allows us to write JavaScript expressions within curly braces {}. This means you can:
Reference variables
Loop over arrays (e.g., using map)
Use operators like the ternary ? :
Note: Statements like if/else or for loops aren't allowed in JSX.
๐ Key JSX Rules:
- JSX is a JavaScript expression, meaning you can store it in variables, use it in functions, and more.
It must have one root element. If you need multiple, use a React Fragment (<></>).
