我需要一个函数isSubset,当给定两个对象时,它会比较它的值并判断一个对象是否是另一个对象的子集.
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
