What is JSX in React?
Cevap
JSX is a syntactic extension of JavaScript that allows writing HTML-like code directly within JavaScript. It gets transpiled into React.createElement() function calls by tools like Babel. JSX makes the code more readable and facilitates UI creation by combining logic and rendering in the same file.

What is the main difference between a functional component and a class component in React?
Cevap
