JavaScript 中的单行语句需要大括号吗？ - Are braces necessary in one-line statements in JavaScript?

问题：

I once heard that leaving the curly braces in one-line statements could be harmful in JavaScript.我曾经听说在单行语句中保留大括号在 JavaScript 中可能是有害的。 I don't remember the reasoning anymore and a Google search did not help much.我不记得推理了，谷歌搜索也没有多大帮助。

Is there anything that makes it a good idea to surround all statements within curly braces in JavaScript?在 JavaScript 中，将所有语句括在花括号内是否是一个好主意？

I am asking, because everyone seems to do so.我问，因为每个人似乎都这样做。
