Script runs a function that doesn’t exist anymore
So there’s a script:
function a(){
alert("lol");
}a()
I run it, then delete the function declaration:
a()The app still runs it as if the declaration is still there. Feels like it caches the function somewhere but I don’t know really.
Cache cleaning doesn’t help.
Restarting AE does help (i.e. it gives “function is undefined error”).How does it work actually and how can I force AE not to do that?

Once you run a script, all the variables that are global are saved in memory until you restart your engine(AE here, but could be extendscript, illustrator etc). In order to not have this problem, you need to store your variables locally. To do that, the best practice in my opinion is use this kind of code as a frame for yours:
(function myScript(thisObj){
//here you write your code
})(this)
This function calls on itself, and all the variables you have are stored inside it. So when it stops running, you have no variable “leftover”.
As a fun fact. You can actually use a variable from a script into another script if it is stored globally.I hope i answered your question.
