TypeScriptSymbols & IteratorsGeneratorsadvanced

What this snippet does

Generators provide a simpler syntax for creating custom iterators using the function* and yield keywords.

Expected output

[ 1, 2 ]

Why practise typing this

Typing symbols & iterators 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.
