I don’t think anyone is going to make it for you. First, this is the snap forum, not a javascript forum, and second, it’s very unclear as to what you’re asking.
i believe the op is asking for a custom js library outside of snap! that could be a text-based sort of adaptation of snap!, just for fun
as for @kikiboom7, in the future, you should probably explain your posts more clearly for the readers, not everyone’s going to understand your suggestion and this line at the end makes the post seem more like you’re showing off you’re idea rather than suggesting it be made:
along with that, i also agree with ego-lay_atman-bay that you should post this on a js forum (i think stack overflow is one) because this forum is mostly focused on the in-editor block coding aspect of snap!, not the js extension, i don’t think a lot of people on the forums know js
