Imagine that you're searching for a solution to a Javascript issue, and you see two search results. One has the answer and links to a working Codepen, and the other provides some conceptual information and links you to MDN documentation so you can figure the answer out for yourself.
Which one are you going to read first? If you picked the first one, does that indicate a dilapidation in reading ability, or that you needed an answer, and the first option provided the best one?
Honestly, if you've written a coding article which doesn't have any code in it, you've probably messed up somewhere along the line. Generally, I'd say it's expected that anything programming related likely has at least a few code samples and a few demos to test out, otherwise its usefulness is rather limited.
