This is an active area that is part of the WebAssembly standards track. See https://github.com/WebAssembly/stack-switching and https://github.com/WebAssembly/meetings/tree/main/stack. This particular feature refers to the integration between JavaScript Promises and stack switching. This is described in more detail in https://docs.google.com/ document/d/16Us-pyte2-9DECJDfGm5tnUpfngJJOc8jbj54HMqE9Y/edit# Blink componentBlink>JavaScript>WebAssembly <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EJavaScript%3EWebAssembly> Search tagsstack switching <https://chromestatus.com/features#tags:stack%20switching>, Promise <https://chromestatus.com/features#tags:Promise>, JSPI <https://chromestatus.com/features#tags:JSPI> TAG reviewhttps://github.com/w3ctag/design-reviews/issues/809 TAG review statusPending Risks Interoperability and Compatibility This spec is backed by a standardization effort. We do not plan to ship the JSPI until it has been standardized by the W3C Wasm WG. However, post standardization, we will depend on all browsers implementing the standard. *Gecko*: Positive (https://bugzilla.mozilla.org/show_bug.cgi?id=1850627) Mozilla have started their own imlementation That doesn't count as a positive signal. Please file for official signals <https://bit.ly/blink-signals> (but that is not blocking for this OT). *WebKit*: No signal *Web developers*: No signals *Other signals*: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? Goals for experimentation This specification is getting close to finalization. We would like feedback from a wider audience as to the utility and convenience of using the API. In addition, we are interested in performance benchmarking in production applications. Ongoing technical constraints None. Debuggability Developers can piggyback on existing DevTools support for Promises to help with debugging JSPI applications. In particular the existing mechanisms for constructing extended stack traces from so-called Promise chains will also include stack traces from JSPI applications. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?Yes Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?No I'm guessing it will be covered by tests, at least eventually?
