Your trycatch sucks - lets fix it

You're not handling errors. You're hiding them.

Every app crashes. Every API fails. Every database hiccups at 2am on a Friday.

The difference between a good dev and a great one? What happens next.

Let's roast your error handling — then make it legendary.

🤦 Level 0: The "Trust Me Bro" Dev

No try/catch at all. Just vibes.

const data = await fetchUserData(userId);

console.log(data.profile.name); // 💥 TypeError: Cannot read properties of undefined

The crime: One bad response nukes the entire app. Users see a white screen. You get a 3am Slack ping.

🐣 Level 1: The Junior — "I Googled try/catch"

try {

  const data = await fetchUserData(userId);

  setUser(data);

} catch (err) {

  console.log(err); // 👈 and... that's it. shipped.

}

What's wrong here?

• 
  console.log in production helps nobody — users still see a broken UI


• No distinction between a 404 and a 500 — every error is treated the same


• The error disappears into the void (or a DevTools tab nobody has open)


• 
  err might be null, a string, or an Error object — you're not checking

The mindset: "At least it won't crash." — Yeah, it just silently breaks instead. Cool.
