I agree, it doesn’t take me personally any longer to write typescript. In fact, it saves me tons of time and endless headaches. I _love_ typescript and use it at work in react and have used it in node for side projects. The benefits are incredible as you mentioned!
I guess it depends on what you’re doing. Setting up the tooling can sometimes be a bit of a pain in combination with other tools which are not designed with typescript in mind from the get go, such as react_on_rails.
If you’re doing a quick mvp in a weekend, I’m still not sure typescript is right. But it really depends on what other tools you are using and how well they integrate. If the mvp works, ya, definitely switch to typescript ASAP. That’s a fine line and really depends on the use case.
