What this snippet does
Partial is ideal for PATCH request payloads where only a subset of fields are updated.
Expected output
{ id: 1, name: 'Bob' }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.
