What this snippet does
Declaring a namespace with the same name as a function merges them, allowing static properties to be attached to the function object.
Expected output
1.0
Why practise typing this
Typing namespaces & merging 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.
