Answer: getfenv() is a type of function. Particually a envirotment function. for a lua coding.
Explanation: What this does it goes thourgh line of code in a particular order.
This means. getfenv is used to get the current environment of a function. It returns a table of all the things that function has access to. You can also set the environment of a function to another environment.
Forgot to include examples of where this could be used. Although not very common uses, there are some. In the past Script Builders used getfenv to get the environment of a script, and setfenv to set the environment of a created script’s environment to a fake environment, so they couldn’t affect the real one. They could also inject custom global functions.
Not entirely sure if this uses getfenv or setfenv, but the use in Crazyman32’s AeroGameFramework is making the environment of each module have access to other modules without having to require them, and having access to remotes without having to directly reference them.
I don't know if this is on your list, but I know for a fact that the Nintendo 64 system (or N64) has a 64-bit architecture.
