Last week I tweeted all of you looking for your best JavaScript Array and Promise tricks, and as always, it didn’t disappoint — I learned quite a bit!

Today’s JavaScript Promise trick is brought to you by Claudio Semeraro: how to use catch to set a default value instead of a try/catch:

// Instead of wrapping this block in a try/catch...
const result = await new Promise(
  (resolve, reject) => reject("Because Stone Cold said so")
// ...use catch to set the default value (100)
.catch(() => 100);

As a trick I really like what’s this brings; as far as readability and maintenance, if you don’t know the trick, you might get confused. What do you think?
