You can also use the `vm.$set` instance method, which is an alias for the global `Vue.set`:

``` js
vm.$set(this.userProfile, 'age', 27)
vm.$set(vm.userProfile, 'age', 27)
```

Sometimes you may want to assign a number of new properties to an existing object, for example using `Object.assign()` or `_.extend()`. In such cases, you should create a fresh object with properties from both objects. So instead of:

``` js
Object.assign(this.userProfile, {
Object.assign(vm.userProfile, {
age: 27,
favoriteColor: 'Vue Green'
})
