At my last job we used a proprietary rapid application development tool to do … everything. It had been used for decades and it’s basically a designer window like Microsoft’s asp net stuff and pseudo code in the background for multi Plattform Desktops and web Applications. The rad in itself is okay: it is written in c++, reasonably fast and has node and js integrations. Buut as said the tool had been used for decades without major refactorings or rewrites or what not. So the codebase was a mix of awful ( you can name variables if so if if is possible ) and straight up outdated. I’d regularly find „commit-comments“ (the integrated vcs is also shit) written before I was born. It was a pain to work with. And we never used the js or node integrations since the new dev lead didn’t know much about developing outside of in said tool which made everything more complicated. So I’m kinda happy to work with js now.
