The lack of strings makes sense, as many different languages and standard libraries have their own implementations of it, that can behave slightly differently.

The lack of strings makes sense, as many different languages and standard libraries have their own implementations of it, that can behave slightly differently. It now puts the implementation of the string to the compilers/linkers, as is generally the case for assembly as well. The lack of a DOM API is something I sorely miss as well. It's currently possible (and not that hard, you can just interact with JS), but comes with such performance overhead that you lose the entire benefit of WASM.
