Well, the first thing I expected to see when I clicked on a function was... the function.
It takes three or four clicks to get that, and the code is at the bottom of a fairly information dense page, where none of the information seems to have any relevance to using the function in your own code.
The other thing I expected to see is some discussion of the implementation, possibly allowing me to choose based on my needs (e.g. if I need to run a function 10,000 times each frame I might choose a different version than if I need to run it occasionally).
However, perhaps my expectations are wrong? Is this a tool for computer scientists to use in mapping the standard functions in various languages, rather than a reference resource for the working coder? The blog post doesn't go into any useful details, it's more like a standard marketing team announcement. They do mention it's part of wider initiative but it's not clear what that will be.
I do agree though that, especially in the age of AI autocomplete tools, I will never find this useful.
... actually, maybe it's a great resource for LLMs to learn from?
