What are the best practices for conditional rendering in Vue?

When using conditional rendering in Vue, it's important to use directives like v-if, v-else, and v-show effectively. v-if is best for rendering elements conditionally, while v-show is better for toggling visibility without removing elements from the DOM.

Can you explain when to use v-if vs v-show?

Sure! Use v-if when you want to conditionally render elements based on a condition, as it adds or removes elements from the DOM. Use v-show when you want to toggle visibility without affecting the DOM structure, as it only changes the CSS display property.

Are there performance considerations I should be aware of?

Yes, v-if can be more performance-intensive because it involves adding/removing elements from the DOM. If you have a large number of elements that need to be toggled frequently, consider using v-show instead.

What about using computed properties with conditional rendering?

Using computed properties can simplify your templates and improve readability. You can compute a value based on your conditions and use that in your v-if or v-show directives.
