Having recently been doing some typescript programming, I can say that 
string interpolation is the kind of thing that grows on you. I could 
live without it, but code with it is much nicer. And more likely 
correct, as has been demonstrated in this thread.

I can say, however, that the barrier to entry of a library version, both 
in imports and in heavy syntax, are enough that I'd never use one.
