I am using watch and created method for the same data.Is it duplicate code? Is there a better way to do it?
props: {
regionList: {
type: Array,
},
},
data() {
return {
regions: [],
};
},
watch: {
regionList() {
if (this.regionList) {
this.regions = this.regionList;
}
},
},
created() {
if (!this.regionList) {
this.getApi();
} else {
this.regions = this.regionList;
}
},

It is what immediate watcher is for:
watch: {
regionList: {
immediate: true,
handler(newVal) {
if (newVal.length) {
this.regions = newVal;
}
}
},
},
created() {
if (!this.regionList) {
this.getApi();
}
},
