WebAssembly's JavaScript Promise Integration (JSPI) API is entering an origin trial with Chrome release M123. JSPI allows WebAssembly code to access asynchronous Web APIs that use JavaScript Promises. To test JSPI, you need to register for an origin trial and generate the appropriate WebAssembly and JavaScript. There are some potential caveats and known issues with JSPI, but they are expected to be addressed before the official release.
