javascript - 将一个对象分配给另一个不带所有字段的对象

Question

我有一个这样的对象

this.currentRegion = {
    latitude: 25.3170013,
    longitude: 55.4748285,
    latitudeDelta: LATITUDE_DELTA,
    longitudeDelta: LONGITUDE_DELTA,
};

和另一个对象

coords = {
    accuracy: 20,
    altitude: 5,
    heading: 0,
    latitude: 25.380599999999998,
    longitude: 55.3992,
    speed: 0,
}

我需要

this.currentRegion = {
    latitude: 25.380599999999998,
    longitude: 55.3992,
    latitudeDelta: LATITUDE_DELTA,
    longitudeDelta: LONGITUDE_DELTA,
}

我尝试了this.currentRegion = Object.assign(this.currentRegion,region.coords);并得到了错误

Attempting to set key on an object that is immutable and has been frozen

Answer 1

this.currentRegion = {...this.currentRegion, latitude: coords.latitude, longitude: coords.longitude}
