Prototyping functions like in javascript to manage a complex prototype

I wish Figma will create prototyping functions so i could create a function template and send him the request variables, just like in javascript, a function that holds set variables, conditions and more.

That will save a lot of prototyping time and the interactions will be managed better for changes.

Currently, if you have a lot of variable interactions then it’s a hard to manage repeated interactions with small changes and adds or even keeping track of the prototype logic.

I wish it will look like this:

1. Creating the variables
2. Creating the functions
3. Applying functions to the prototype.
4. Managing logical functions for changes

Check out my screenshots to understand my pain of managing all of this.
