Italicizing non-literal syntax?

まだ誰も着手していません。

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.

まず、リンクされた modifying-document の記事にある構文例を確認し、MDN appendChild の例と比較します。チュートリアル全体でリテラルでない構文に斜体を適用する範囲を決定し、その規約を文書化して、関連する例を一貫して更新します。
