Making all properties optional with Partial in TypeScript

TypeScriptUtility TypesPartial & Requiredintermediate

What this snippet does

Partial<T> constructs a type with all properties of T set to optional.

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.
