What this snippet does
this is determined at call time — when you detach a method and call it as a plain function, this is no longer the object.
Expected output
Hi, I'm Alice Hi, I'm undefined
Why practise typing this
Typing objects 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.
