_.keys
should do the trick.
_.keys
应该做的伎俩。
_.keys(object)
Creates an array of the own enumerable property names of
object
.
_.keys(object)
创建 的自己的可枚举属性名称的数组
object
。
Example:
例子:
console.log(_.keys({ "tab1": "1" , tab2: "2"}));
console.log(Object.keys({ "tab1": "1" , tab2: "2"}));
// Outputs:
// ["tab1", "tab2"]
// ["tab1", "tab2"]

Side-note:
边注:
Remember that the keys of an object are not necessarily ordered, and so they can come back in any order the host chooses.
请记住,对象的键不一定是有序的,因此它们可以以主机选择的任何顺序返回。
