What frameworks do you use for prototypes?
In order to quickly create a prototype with good frontend what do you use besides React
I tend to follow the 'make it work, then make it pretty' school of thinking but it really depends on what you're building - since you've mentioned React, can we assume you're looking for some kind of web solution?
I prefer Svelte and Inferno mostly. However, for quick prototypes or side projects that I know I'm not going to need, I use a completely new framework, to experiment and have fun while learning something new.
