What this snippet does
The typeof operator on a class name extracts the type of the class constructor itself, rather than an instance type.
Expected output
User {}Why practise typing this
Typing type manipulation 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.
