I want to do something every time console.log executes. Can I add an event listener to console.log or is monkey patching the only approach? If monkey patching is the best approach, how to I monkey patch without creating infinite recursion?

Yes, you will need to do monkey patching. And instead of "recursively" calling theconsole.logfunction again, you will need to store a reference to the original function and call that.

You could use a wrapper function that wraps the behaviour of console.log.
Something like:
const logWrapper = (logString) => {
// DO SOMETHING HERE
console.log(logString);
}
and call that new function instead.
You could also change the definition of console.log, but I wouldn't advise that.
