To be precise, I meant "why not use ..." comparison. I don't mind why the project was started. Whatever the reason, well done for getting it to this stage! But the other side - why should we be interested - is interesting :-)
One reason could be that it might be easier for node.js devs to read and understand its source code. I don't use the software nor have read its source code, though.
Sometimes I think that there are not enough of real problems to solve in the js world.
Too many people pumped into a tight space of the frontend development are creating in there another copy of the whole infrastructure while limited by the tools that weren't designed for that.
