This post is a joke right? The world has moved on. JS *is* the target, but it is *no longer* the source.
There is so much more to software development than the how quickly one can vomit code into their editor of choice. If typescript is slowing you down, your code is *bad*. End of story.
Continually pretending that types don’t matter is laughable. The thousands of dynamic language projects with littered with type-hints, type-assertions, and type-verifying unit tests proves otherwise.
