Learning Lodash 4.0 (Video 8)

This video tutorial covers the creation of a new API endpoint to display tag totals in a recipe application. It begins with a recap of the previous video, where an input was created to filter recipes by username using Lodash's reduce method. The tutorial then guides viewers through building an API endpoint using Lodash methods like countBy and map to calculate tag totals. The video also demonstrates how to integrate a new component for displaying these totals on the front end. Finally, it concludes with a summary and a preview of the next video, which will focus on adding search capabilities to the API.
