In this release, React is dropping support for Internet Explorer, which is going out of support on June 15, 2022. We’re making this change now because new features introduced in React 18 are built using modern browser features such as microtasks which cannot be adequately polyfilled in IE.
React 18 use messagechannel to schuduler, and this is macrotask ? not microtasks?

Is the doc wrong ?
