TypeScript is a version of JavaScript that lets you add types — so you can catch mistakes before they become bugs.
It looks and feels like regular JavaScript, but you can say things like “this should always be a number” or “this object should have a name and email.” That way, the computer can alert you before you run your code and find out something broke. It’s optional, but super helpful when working on big projects or in teams.
Think of it like putting labels on everything in your fridge — you’ll know what’s what, and won’t accidentally use salt instead of sugar. TypeScript doesn’t stop you from writing messy code, but it gives you a map and warning signs as you go.
