Are there any good tools for a generic Javascript reversing workflow. I use the term decompile loosely here but with typescript and so many powerful and ubiquitous frameworks, this is starting to get interesting. Of course there are tools to unminify and reformat Javascript and the browser dev tools are helpful but it seems we haven't seen anything with a more automated and better level of sophistication. Which is really useful when looking for security vulnerabilities which are likely common place in modern web apps.
