OP was clearly asking what makes someone a high quality engineer, so focusing on his specific word choices to respond with the "hello world" of web development is a total non-answer in my opinion.
Skills that amount to the "hello world" of web development can be worth hundreds of thousands of dollars to an expanding or new company, but are worth less than pennies to a Netflix. Trying to measure quality without context is, imo, one of the biggest drivers to the cluster fuck that is tech recruiting.
