Modern JavaScript from the Beginning - Second Edition - Set Calorie Limit

The video tutorial explains how to modify a hardcoded limit using local storage by adding an event listener to a form. It covers creating a set limit method, processing form data, and updating a tracker. The tutorial also demonstrates closing a Bootstrap modal and accessing public methods in a tracker class. Finally, it shows how to update and display a new calorie limit, preparing for further work with local storage.
