What this snippet does
The for-await-of loop pauses execution until the next promise from the async iterator resolves, ideal for streaming data.

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.
