Also : avoid using IT terms in examples (or "self-reference"), it can be confusing. In examples choose a very different field : animals, cars or anything, so that there is a very clear difference between language keywords (what needs to be learned) and the dummy data treated (what can be forgotten after reading). An example not to follow : https://developer.mozilla.org/en-US/docs/Web/API/Web_components/Using_templates_and_slots#using_the_element-details_custom_element_with_named_slots https://developer.mozilla.org/en-US/docs/Web/API/Web_compone... Here we are trying to explain templates and slots, with "slot" as an html attribute and the dummy data is... "slot". This kind of confusion is useless and makes it more difficult. Almost as if the goal was to be difficult.
