查找某个对象是否为javascript中另一个对象的子集

我需要函数isSubset，该函数在给定两个对象时比较其值，并判断一个对象是否为另一个对象的子集。

object1 = { pickUpLocation : {city : 'Hyderabad', state: 'Telangana' }};
object2 = { dist : 322, pickUpLocation:  {city : 'Hyderabad', state: 'Telangana' }};

isSubset(object1, object2); //should return true

object3 = { pickUpLocation : {city : 'Chennai', state: 'Telangana' }}
object4 = { dist : 322, pickUpLocation: {city : 'Hyderabad', state: 'Telangana' }}

isSubset(object3, object4) //should return false as city's value is different

---

解决方案

使用对数isMatch

_.isMatch({prop: 'object', id: 3}, {prop: 'object'})

在对象和源之间执行部分深度比较，以确定对象是否包含等效的属性值。
