[@types/emscripten]: preRunmissing arg

[jeswr]

Currently the type signature of preRun is (() => void)[]. Instead it should be more like

type singlePreRunType = ((arg: SWIPLModule) => void) | (() => void);
type preRunType = singlePreRunType | singlePreRunType[] | undefined;

as can be seen in the usage in https://github.com/eyereasoner/eye-js/pull/79/files

Also reported in SWI-Prolog/npm-swipl-wasm#13

Do we defined those types here in this repo? (i'm not sure this is the correct repo for this bug).

[jeswr]

Indeed type definitions are hosted in https://github.com/DefinitelyTyped/DefinitelyTyped/. However, a bug report in that repo is likely just to get lost in the noise of all the other packages that the type definitions are hosted for - which is why I opened it here.

But the maintainers of this repo don't maintain those types so I'm not sure what we should do. Do you want to send them a PR maybe?
