如何在lodash中使用includes方法来检查对象是否在集合中？

 

_.includes([1, 2, 3], 2)
> true

 

_.includes([{"a": 1}, {"b": 2}], {"b": 2})
> false

 

_.find([{"a": 1}, {"b": 2}], {"b": 2})
> {"b": 2}

 

var a = {"a": 1}, b = {"b": 2};
_.includes([a, b], b);

 

({"b": 2} === {"b": 2})
> false

 

_.some([{"a": 1}, {"b": 2}], {"b": 2})
> true
