Lazy Loading constants

The Optimizer can be used to lazy-load data, not just functions. The benefit of doing that is that lazy loading any part of your application becomes easy.

Use the stand-alone $() function to mark the data that you wish to lazy load. The $() function returns a QRL that is a reference that can be serialized by Qwik and that can later be resolved into the original value.

Example

Load the data representing the message lazily as part of the click listener.

For this exercise imagine that we wish to lazy load the 'Hello World!' string. Use the $() function to mark the string as lazy-loadable. Then use await to resolve the lazy-loadable value.

Go to the Symbols tab and examine how the code was broken down into parts.
