Wow!! What an amazing post. Many programmers should see this.

It's very common for me to get projects that programmers don't handle errors well.

This post will help me give direction to new developers on my team, thanks so much for sharing!

Thanks Bruno!

I'm writing a post series in which I'm summarize many tips that I've taught for years 🙃

I was wondering if Typescript supports a update(): Account throws UpdateException {...} style syntax. It's been suggested, but not supported yet:

Great post ✌️✌️✌️,
I have been using a technique for handling errors...I would alert (Material UI Modal) the user showing the error message with a retry action button...it has been working for me so far, do you have a better approach?

Awesome post, it may be worth noting that there is a change coming to the spec that allows developers to ignore the specifics of the error, and do whatever they want in the catch:

try {
  someThrowableMethod();
} catch {
  uhOhTellUserWeErrored();
}

We no longer have to ask the engine what the error was, and instead just react to it.

This change has landed yet, but it's on its way!

Again, great article!
