What this snippet does
localhost refers to the container itself, not the host or a sibling container.
Expected output
wget: can't connect to remote host: Connection refused
Why practise typing this
Typing networking 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.
