WebAssembly JavaScript Promise Integration
WebAssembly JavaScript Promise Integration (JSPI) is a technology that allows WebAssembly applications to access asynchronous Web APIs; even from synchronous code. It works by suspending the WebAssembly code when it calls a WebAPI import that returns Promises. This is based on a specification that is currently being standardized in the W3C's WebAssembly Community Group (see https://github.com/WebAssembly/js-promise-integration)
