Picking specific properties from an interface in TypeScript

TypeScriptUtility TypesPick & Omitintermediate

What this snippet does

Pick<T, K> creates a new type by selecting only the specified keys K from T.

Expected output

{ name: 'Alice' }

Why practise typing this

Typing utility types 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.
