What is the difference between reactive and ref in Vue?

What is the difference between reactive and ref in Vue?

In Vue, reactive creates a reactive object, while ref creates a reactive reference to a value. reactive is used for objects, and ref is for primitive values.

Can you give me an example of when to use each?

Sure! Use reactive when you have a complex object that you want to track, like a user profile. Use ref for simple values like a string or number, such as a count.

What happens if I use ref with an object?

If you use ref with an object, the object itself will be wrapped in a reactive reference. You will need to access the object using .value.

Are there any performance differences between them?

Generally, both are efficient, but reactive can be more performant for large objects since it tracks changes at the object level.
