Creating a dynamic string-to-any cache in TypeScript

What this snippet does

Index signatures are ideal for hash maps or caches where keys are generated dynamically at runtime.

Expected output

{ name: 'Bob' }

Why practise typing this

Typing objects and interfaces 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.
