It takes a good programmer to write it, and most good programmers avoid JavaScript, unless forced to use it for their day job. in that case, there is no incentive to speed up the part of the job that isn't writing JavaScript.

Some of us, already have all the speed we need with Java and .NET tooling, don't waste our time rewriting stuff, nor need to bother with borrow checker, even if it isn't a big deal to write affine types compliant code.

And we can always reach out to Scala or F# if feeling creating to play with type systems.

Nonsense.
