FAQ (Frequently Asked Questions)

How do I add if condition in LWC?

In LWC we have if:true|false directive like we used aura:if in aura components. For conditional rendering we just need to add the if:true|false directive to a nested tag that encloses the conditional content.

How do you use each in LWC?

To use for:each, assign the Array to for:each and iterator variable to for:item. Then, we can use this iterator variable to access the elements in the Array.

Can we use multiple templates in LWC?

You may want to render a component with more than one look and feel, but not want to mix the HTML in one file. In this case, you can import multiple HTML templates and write business logic that renders them conditionally.
