我有这个javascript对象:

var countryArray = [{
 "country" : 'Indonesia',
 "state" : ['DKI','Bali'],
},
 {
 "country" : 'Malaysia',
 "state" : ['Penang','Johor'],
}];

var newArr = [{ "country" : 'Malaysia', "state" : ['Kelantan'] }]

如何合并或添加newArr到相关的CountryArray.

预期结果 :

var countryArray = [{
 "country" : 'Indonesia',
 "state" : ['DKI','Bali'],
},
 {
 "country" : 'Malaysia',
 "state" : ['Penang','Johor','Kelantan'],
}];
