Great post! Love the flexibility this gives to the end user.

Out of interest, did you consider using web workers to execute the user defined JS code. Workers don't have access to the DOM and limited access to methods and properties on the window object. Example here https://jsbin.com/vicayavumi/1/edit?js,console

@LoueeD thanks for the feedback!

An interesting suggestion – I did in fact look at web workers but I just found that they still gave too much access to the user's device. The main concern being the fact that users could write logic that sends data (that's considered private by privacy laws) to other servers which is going to be a nightmare to try to moderate in the project that I'm working on.
Nonetheless, it's absolutely an alternative solution that's much faster but does sacrifice control over the user's privacy and what can be accessed.
