Idiomatic is the word the parent was looking for. The base word is idiom.

It was probably the intent of the parent to mean 'making use of the particular features of the language that are not necessarily common to other languages'.

I'm not a programmer, but you appear to give good examples.

I hope I'm not teaching you to suck eggs... {That's an idiom, meaning teaching someone something they're already expert in. Like teaching your Grandma to suck eggs - which weirdly means blowing out the insides of a raw egg. That's done when using the egg to paint; which is a traditional Easter craft.}

I actually did find "idiomatic" when I looked it up, but I honestly still didn't quite grasp it from the cambridge dictionary. Thanks for explaining it in a way I understand.

In programming Idiomatic is used to reference a programming language’s “best practices” and “style guide”. Obviously programming languages can solve problems in many different ways, but they often develop a “correct way” that matches their design or the personality of their influential community members. Following this advice is Ideomatic. Next time your coworker has their style wrong you can say “I don’t think this is Idiomatic” :D
