- [Object.keys(obj)](mdn:js/Object/keys) -- returns an array of keys.
- [Object.values(obj)](mdn:js/Object/values) -- returns an array of values.
- [Object.entries(obj)](mdn:js/Object/entries) -- returns an array of `[key, value]` pairs.
+- [Object.keys(obj)](mdn:js/Object/keys) —— 返回包含所有键的数组。


『返回包含所有键的数组。』 => 『返回一个包含该对象全部的键的数组。』

“返回包含所有键的数组”这句话中的“所有”一词容易引发歧义。一个解释是“归XXX所拥有”，一个解释是“全部的”。
为避免歧义，建议改为“全部”

-The second difference is that `Object.*` methods return "real" array objects, not just an iterable. That's mainly for historical reasons.

『第二个区别是 Object.* 方法返回的是「真正的」数组对象，而不是可迭代项。这主要是历史原因。』 => 『第二个区别是 Object.* 方法返回的是「真正的」数组对象，而不仅仅是一个可迭代项。这主要由于是历史原因。』
