🧒 Explain like I'm 5
JSX is like a special shorthand note that your computer translates into real instructions. Imagine writing a recipe using simple icons instead of full sentences — it's much faster to read and write. A tool called Babel reads your JSX and converts it into standard JavaScript that the browser understands, just like translating the icons back into full sentences.
