How do I use dynamic classes in Vue.js?

In Vue.js, you can use the :class binding to dynamically assign classes based on conditions. For example, you can bind an object or an array to the :class attribute.

Can you show me an example of using an object for dynamic classes?

Sure! Here's an example: <div :class="{ active: isActive, 'text-danger': hasError }"></div>. This will apply the 'active' class if isActive is true and 'text-danger' if hasError is true.

What about using an array for dynamic classes?

You can use an array like this: <div :class="[classA, classB, { 'is-active': isActive }]">. This allows you to combine static and conditional classes.

Are there any performance considerations I should be aware of?

Yes, while dynamic classes are powerful, excessive use can lead to performance issues. It's best to keep your class bindings simple and avoid complex computations in the template.
