Lesson 06
Why it's worth it
A bit more to write up front buys you four things that compound as a project grows.
THE PAYOFFSCatch bugs early — mistakes surface as you type, not on a user's screen. Editor superpowers — it knows your types, so it autocompletes and suggests. Code that explains itself — labels say what each piece expects. Safe to change & grow — change one thing and it flags every spot that needs updating.
THE HONEST TRADEThe cost is real: a little more to write up front, plus a build step. For anything past a quick script, most teams find the early bug-catching more than pays for it. That's the whole trade — and now you can see both sides of it.
