Polling an API asynchronously in TypeScript

TypeScriptAsync IterationAsyncGeneratorsadvanced

What this snippet does

Async generators are perfect for creating infinite polling loops that can be paused and canceled by stopping iteration.

Expected output

true

Why practise typing this

Typing async iteration code builds muscle memory for the symbols and indentation TypeScript uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
