What this snippet does
Symbols are guaranteed unique primitives — two Symbols with identical descriptions are still not equal to each other.
Expected output
false symbol Symbol(id) id
Why practise typing this
Typing symbols 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.
