In my experience folks can be reasonably productive essentially immediately in a language they've never touched if they're diving into an existing code base. Give them a machine that's already set up like the other developers, point them at a couple easy bugs or features, do some code reviews, and yes they'll be slightly slower through this process than someone that's already familiar with the stack, but not much.
I think this is only true if what you're working on is simple, like crud apps.
It takes longer to be intimately familiar with a language's concurrency model, pros and cons of major libraries and frameworks and the ability to make such decisions quickly and without learning hurdles, etc.
