强制使用 String.trimStart() 和 String.trimEnd() 而不是 String.trimLeft() 和 String.trimRight()。

¥Enforce the use of String.trimStart() and String.trimEnd() over String.trimLeft() and String.trimRight().

虽然 String.trimLeft() 和 String.trimRight() 是 String.trimStart() 和 String.trimEnd() 的别名，但仅使用后一对可确保一致性，并且更适合其与方向无关的措辞。

¥While String.trimLeft() and String.trimRight() are aliases for String.trimStart() and String.trimEnd(), only using the latter pair ensures consistency and is preferable for their direction-independent wording.

请注意，String.trimStart() 和 String.trimEnd() 方法不接受任何参数。传递给这些方法的任何参数都将被忽略。有关更多详细信息，请参阅 MDN 文档：

¥Note that String.trimStart() and String.trimEnd() methods do not take any parameters. Any arguments passed to these methods will be ignored. See the MDN documentation for more details:
