For you maybe. For me the response is "walkLength???" WTF is 
that? Does this imply a length restricted forEach?

I've never seen "walk" or "traverse" being used for indicating 
O(n), it is usually used to indicate something you can utilize in 
order to traverse a data-structure. That's how the terms are used 
in CS.

"Walk" is an imperative. "walk length" indicates "walk the length 
of", not "calculate the length of".

But naming functions is often more difficult than writing the 
code. (not a joke)
