Advanced Bubble.io Tutorial: How to combine multiple data sources into a single repeating group

We use an example of creating a cart for an online store in this demonstration.

In this video, we show you how to combine multiple data sources into one using lists, JSON-like syntax, and your own Bubble API.

We show you how you could build a system that allows your user to get immediate frontend results that only saves the data once the user confirms their selections. Reduce workload units, time, and customer frustration. Build your app the right way!

Hello, I just start learning bubble for last 6 month and right now on the step of build cart page for my marketplace.
What I have done is the cart page already accept the product, edit the qty and delete the product.
but I found that the edit qty feel so heavy and make the page slow ( I believe something wrong with my workflow ).
by watching your video make me interest to learn more "technical" stuff in bubble.
can you share the full and deep process when you build the cart page, the concept, the fundamental I need to learn.
Thank
