I understand the author's overall point, but does a variable declaration really need to be rewritten 10 times to do its job? This feels like an apples to oranges situation. Maybe the 10:1 rule could apply to a component or a function or maybe the context of the line of code should be taken into account. Lots of lines of code are really the equivalent to punctuation in prose - important but ultimately an adornment.
