What this snippet does
Stages can be referenced by index, though names are far more readable in practice.
Expected output
built
Why practise typing this
Typing multi-stage builds code builds muscle memory for the symbols and indentation Docker 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.
