Functions
hi, if i have a function, and i need to pass the users id who executed it, how can i do that?
TL;DR
Developers can access the user ID of the person who executed a function using the `APPWRITE_FUNCTION_USER_ID` variable. This can be retrieved using the code `const userId = res.variables['APPWRITE_FUNCTION_USER_ID']`. 
To pass the user ID of the person who executed the function, you need the APPWRITE_FUNCTION_USER_ID variable
TypeScript
const userId = res.variables['APPWRITE_FUNCTION_USER_ID']
This variable will automatically contain the user's ID who executed the function.
thank you! is there a documentation for other variables like this aswell?
