What this snippet does
Recursive type aliases and interfaces handle nested schemas flawlessly, as long as the compiler can lazily evaluate them.
Expected output

Why practise typing this
Typing type system limits 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.
