When working with objects in components like demonstrated below:
data() {
return {
person: new Person("Kireeti", 26)
}
},
mounted() {
this.person.celebrateBirthday();
}
This method is arguably more advantageous compared to simply incrementing
this.person.age += 1</code within the component.</p>
<p>The rationale behind this is that while increasing a person's age by 1 is straightforward, there could be more intricate conditions for other objects. Perhaps you may want to introduce constraints within the <code>celebrateBirthday
function or make additional changes to the person's attributes beyond just altering their age.
It is preferable not to handle such logic within a Vue component, especially considering that other components may also utilize instances of the Person class. Keeping this logic within the class itself appears to be the more suitable approach.
Potential Concerns
Issues relating to object references typically stem from matters of reactivity. For instance, if the Person class includes an array of friends, and your component relies on monitoring its changes through code like:
<friend-component v-for="friend in friends" :data="friend" />
You must exercise caution when modifying the internal friends array within the person object in a manner that ensures compatibility with Vue's reactive tracking mechanisms. It is important to note that neither Sets nor Maps can be reliably used for this purpose, and there exist several other limitations as well. Additionally, remember to specify {deep: true} when observing modifications to objects.
Nevertheless, whether it pertains to variables associated with your Vue component or those belonging to an object, the principles regarding object references remain consistent without any major drawbacks as far as my knowledge extends.
