In this lesson, you'll learn how to implement smooth state transitions in your web applications using the browser's built-in View Transitions API. We'll create a simple example that demonstrates how to animate between different text states with just a few lines of code - no external libraries required. This powerful native API makes it easy to add professional-looking transitions to your user interface, enhancing the user experience with minimal effort.

[00:00] We have an array of messages and index to track which one we want, and we want to click on this button to trigger a transition between each message. So we can use the document start view transition API, and I want to adjust the index first, and then all I have to do is click this button and it's doing a smooth transition every time I click, changing the content from one message to the next. We can also get the transition and use the transition so when it's ready we can adjust the button and when it's finished we can do something else to the button. Blur and focus would be great for keyboard state, but let's visibly disable the button and then once it's done we can re-enable the button. So now when we click you can see once the transition starts the button goes a bit transparent.
