Why doesn't the JavaScript transpiler use BigInt "under-the-hood" to store Ints?

Because they are very slow and break interop.

break interop.

Do you mean they aren't backwards-compatible? They're from ES2020. Does the JS need to be IE11-compatible?

They are (usually) not compatible with JSON afair.

They are also very slow on JS for common int operations, AFAIK. So they are not a good default until you need very large ints. There is https://hex.pm/packages/bigi for that.
