I think it’s a bit of an outdated stereotype from back in the day when this kind of frameworks started popping up left and right.
It was a major shift from jquery-based sites/apps which scared many people away from diving deeper into front end. Nowadays you can stick to one of the major three and you’ll be fine for the foreseeable future. This new Vue version is the most disruptive change we’ve had since a long time ago in the fe framework space and it’s still ok to get used to.
This is great news, Vue 3 looks much better than its predecessor.
However, I had to migrate a Vue 2 + TS app to Vue 3 and their guide at the time was pretty underwhelming. Props to Evan for dedicating time to migrate a sample app and publish the migration as commits, but the app was quite basic and dependency-free so I had to figure out a lot of stuff on the go. The compatibility build actually slowed down my progress as it took me a lot to figure out that I didn't actually benefit much from it and could just drop it. Till this day I don't have a clear idea about what @vue/compat is for.
Hopefully, with them pushing Vue 3 as the new default, there will be more detailed how-tos available.
That's been my experience, as well. I got everything working because I'm very familiar with Vue, but I did end up removing a lot of TypeScript from my app just to make it all easier. Luckily, Vue makes it easy to mix and match JS and TS (for better or for worse).
I jumped on the React bandwagon because I didn't like the Typescript support in Vue 2, and did not see much improvements for V3. Vscode Vetur was slow and unable to do full typechecking in Vue files. Much of my code was based on Vue Class Components, which was not going to be compatible with the new API. Vuex did not seem to be going in the Typescript direction either. A bit sad if you consider Vue 3 is written in Typescript.
TS support has been improved dramatically with volar VSC extension and vue-tsc CLI tool.
When that was released (I’d need to check when but in 2021 or even late 2020) my React FOMO disappeared as I get full TS support in script and template tags.
Composition api + VueUse are wonderful together.
I’ve been lucky to start fresh with vue 3 mid 2020 (in beta?). But I and can understand frustration to migrate.
