well that's some scary typescript syntax. i didnt know a string constant at the top of a function could change the operation.

or is this some extra compilation step to rewrite the code?

"use strict" has been around since 2009. That being said, this is not a TypeScript or React feature but yet another black box magic NextJS feature to try to lock you into the Vercel ecosystem.

Must be some compile step. Reminds me of “use strict”.
