I didn’t touch TypeScript once in the last 3 years. I stopped using it when I changed my job, from Angular 4 back to jQuery, AngularJS, and forth to VueJS.
- Did I miss it? Not once.
- Did I like it when I had to use it? I did.
In the end, it seems to me that the benefits of TypeScript are less relevant than the drawbacks. Which is essentially one: development slowness, for having to get types right, when wrong types are hardly so subtle errors that you wouldn’t detect otherwise.
