Feature request

Allow WebAssembly i64 to be used in JavaScript; using the conversion to BigInt.

What is the expected behavior?

More info in https://github.com/WebAssembly/JS-BigInt-integration.

What is motivation or use case for adding/changing the behavior?

To move the proposal forward we need some toolchain support (WebAssembly/JS-BigInt-integration#15), currently Webpack ensures that no I64 flows in JavaScript.

How should this be implemented in your opinion?

Behind a flag!

Are you willing to work on this yourself?
yes
