I took a look at rescript's facillities for migration from JS and at step 1 (https://rescript-lang.org/docs/manual/latest/converting-from...), it tells you:

> First, copy the entire file content over to a new file called src/Main.res by using our %%raw JS embedding trick: > %%raw(`const school = require('school'); etc. `)

I stopped reading there - I'm sorry but that is horrifying. Wrapping JS in in a big backtick string?! No. That's even worse that Dart-JS interop.
