parallel await in JavaScript

JavaScriptAsync/Awaitsequential vs parallelintermediate

What this snippet does

Awaiting in a loop runs each promise one after another — use Promise.all to run independent async tasks concurrently.

Expected output

sequential done
parallel done

Why practise typing this

Typing async/await code builds muscle memory for the symbols and indentation JavaScript 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.
