Add Total Calories

The video tutorial explains how to manage total calories in an app. It begins by introducing the concept of total calories and how to add items to it. The tutorial then guides through creating a function to calculate total calories by looping through items and updating the total. It also covers updating the UI to display the total calories and discusses initializing the app state. Future plans include implementing an edit state for the app.

• The app will close

• The app will refresh

• The total calories will reset

• The edit button will disappear and an update button will appear

What is the next step after implementing the edit state in the app?

• Optimize the app for mobile devices
