Bypassing excess property checks via variables in TypeScript

TypeScriptObjects and InterfacesExcess Property Checksbeginner

What this snippet does

Assigning an object via a variable bypasses excess property checks as long as the required properties exist.

Expected output

{ x: 1, y: 2 }

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.
