When I had to get up to speed on a new language, it was very helpful. It's also great to write low to medium complexity scripts in python, powershell, bash, and making ansible tasks. That said I've been programming for ~30 years, and could have done those things myself if I needed, but it would take some time (a lot of it being looking up documentation and writing boilerplate code).
It's also nice for writing C# unit tests.
However, the times I've been stuck on my main languages, it's been utterly useless.
I have a feeling whoever is tasked with that will be some kind of variant of this
