Comparing type and interface syntax in TypeScript

TypeScriptType Aliases vs Interfacesbeginner

What this snippet does

Both type aliases and interfaces can define object shapes, but they differ in extension capabilities.

Expected output

{ name: 'test' } { name: 'test' }

Why practise typing this

Typing type aliases vs 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.
