btw, seems threads are coming to WebAssembly, at least in Chrome, judging from
(btw, interesting API table there)
We’ve outlined here the status of Web Platform substitutes for each of the APIs exposed to §NaCl. Additionally, the table lists the library or option in Emscripten that offers the closest substitute.
We expect to add shared memory threads support to WebAssembly in 2017, as threads are crucial to matching §NaCl’s most interesting use cases. Migration items which assume forthcoming threads support are marked below. If your application’s flow control relies heavily on blocking APIs, you may also find threads support is required for convenient porting.
While we’ve tried to be accurate in this table, there are no doubt errors or omissions. If you encounter one, please reach out to us on firstname.lastname@example.org
