Submit Issue to react-native about WebAssembly

[martinheidegger]

There is a fix in the test setup for broken/missing WebAssembly support in the react-native for iOS system:

sodium-javascript/test.js

Lines 7 to 14 in 6322cb1

	// iOS defines a WebAssembly global, but doesn't provide a way to create instances
	// We shold delete the WebAssembly global in that case so that the tests pass
	if (typeof WebAssembly !== 'undefined' && global.WebAssembly) {
	const canMakeInstance = global.WebAssembly.Instance || global.WebAssembly.instantiate
	if (canMakeInstance) {
	global.WebAssembly = undefined
	}
	}

- This should be reported to react-native with the hopes to make it unnecessary to have that fix in future.

Looking into this now

I think there's a bug in my logic actually. 🙃

Working on making a minimal test case to submit in the RN github issue.

I have a hypothesis that maybe WASM is actually supported but there's something weird when loading? 🤔

BLocked by faceboook for now, but we have a workaround

Even if facebook reacts on this it will take ~ half-a-year until this may work. Is it possible in a react-native setup to just set global.WebAssembly = undefined?

@martinheidegger Yes, I've done it in the shim.js file within the hypercore-rn repo.
