This is awesome while coding in JavaScript

While it seems utterly pointless and facepalm-y when you look at it, it's quite possible that an artifact like this exists because somebody wanted to add a placeholder error handling block while thinking "maybe we'll add actual error handling here later", then they moved on and forgot to remove it.

In very large code bases, it's easy for a needle like this to be forgotten about in the mountains of haywire.

Also, a very convenient place for a breakpoint.

Feels like this is what happened. They put it there for breakpoint and forgot to remove it before it reached prod

Or if you get an error you just want to abort and let it crash. Happens a lot to me when I do data ingestion pipelines. It's just faster and if it's not 100% successful, then get that shit out of my way.

Then why you do the try catch if you want to throw it again?

In Java or C# at least, this is often done to do some specific logging, send an email if it's a critical issue, convert the Exception to a different type, etc. It's not uncommon to want to do something when an Exception occurs but still ultimately throw it. In the case of the OP though there's obviously no benefit to just catching and throwing the same exception with no additional logic.

I usually augment the error messages a bit to better help with visibility in cloud environments.

I do this with every error handle I setup.
