Suppose I’m building an internal dashboard, with requirements that change over time, and the developers come and go (i.e. I don’t want a steep learning curve).

React became the language that all developers learn to call themselves “Frontend Developers”.

Sorry for the mediocre approach, but the alternative has to be so much better that it would worth paying a developer that never learned it to use it.

Typescript was such a success because it’s really not that different from the Javascript that programmers already know.
