Italicizing non-literal syntax?

Personne n'a encore pris cette issue.

How about, when showing syntax like:

node.append(...nodes or strings) – append nodes or strings at the end of node,
node.prepend(...nodes or strings) – insert nodes or strings into the beginning of node,

that "node" (in this case), or whatever syntax is not literal, that is, that stands for some general type of thing, be put in italics, i.e., in this case, to have instead:

_node_.append(...nodes or strings) – append nodes or strings at the end of node,
_node_.prepend(...nodes or strings) – insert nodes or strings into the beginning of node,

(From: [https://javascript.info/modifying-document](url))

I think that would make the meaning of the syntax clearer. Also, this is what MDN does in their Syntax descriptions, e.g.:

_element_.appendChild(aChild);
[https://developer.mozilla.org/en-US/docs/Web/API/Node/appendChild](url)

This would also address some of my earlier concerns with the use of "str", "array", "obj", etc. from a couple months ago.

Commencez par examiner les exemples de syntaxe de l’article modifying-document associé et comparez-les avec l’exemple MDN appendChild. Déterminez dans quelle mesure l’italique doit être appliqué à la syntaxe non littérale dans l’ensemble du tutoriel, puis documentez la convention et mettez à jour les exemples concernés de manière cohérente.
