What this snippet does
Destructuring params with defaults makes function signatures self-documenting and removes the need for options.x inside the body.
Expected output
Alice, 30, user Bob, 0, admin undefined, 0, user
Why practise typing this
Typing destructuring code builds muscle memory for the symbols and indentation JavaScript 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.
