 > I don't know if this has been mentioned, but in regard to `sprintf()`:
 in JS that is already using Underscores anyway, it is possible to use
 Underscores templates to do this. I have done this before.

 Interesting! Thanks for sharing. Loading 16KB of JS (the size of
 underscore.min.js) for using `sprintf()` is not a viable solution for core
 though. That's why I've opened #38147 to suggest adding the lightweight
 sprintf.js library instead.
