Computed Properties vs Methods in Vue.js

What is the difference between computed properties and methods in Vue.js?

Computed properties are cached based on their dependencies, while methods are executed every time they are called.

Can you give me an example of when to use a computed property instead of a method?

Sure! Use a computed property when you need to derive a value based on other reactive data, like formatting a full name from first and last names.

Are computed properties more efficient than methods?

Yes, computed properties are generally more efficient because they only re-evaluate when their dependencies change, unlike methods.

What happens if I use a method instead of a computed property?

If you use a method, it will run every time it's called, which can lead to unnecessary computations and performance issues.
