Italicizing non-literal syntax?

还没有人认领这个 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.

首先查看链接的 modifying-document 文章中的语法示例，并将其与 MDN appendChild 示例进行比较。确定在整个教程中对非字面语法应用斜体的范围，然后记录这一约定，并一致地更新相关示例。
