Why is it crazy? Doesn’t a lot of the office tools also use react these days (maybe just the online ones but still)?

I’ve only recently started working with react, but so far it’s been the best experience I’ve had working with GUI in decades of working with different things.

I’ve always been what you’d call a full stack developer, but I’ve always very much not been the front end design developer, and react with bootstrap and font awesome is the first time I’ve been able to effortlessly create GUI stuff that doesn’t look like it should’ve been made by a front end design type.

So to me this is not at all surprising or crazy. It’s simply what happens when you have a really effective tool that a lot of people know how to use.
