Notes

The AsyncContext proposal adds an API that shares similar scopes with Node.js stable API AsyncLocalStorage into the ECMAScript. Moreover, AsyncContext adds generator/yield support and making the semantics of future using declaration support more intuitive in generator function bodies.

The proposal will expand the usages of Node.js stable API AsyncLocalStorage to the Web and other JS runtimes.
