I found out recently about indexedDB that exists in the browser! and wanted to make a video tutorial about it. I got say the API is clunky but that did not stop me from making the video. I first explain the eventing that get triggered when you open the database, onupgradeneeded, onsuccess, onerror and when each are triggered. Then we dive into creating objectstore, then transactions both writing and reading. Pretty cool technology. We are using Javascript on the browser and visual studio code. Enjoy the tutorial guys 

The tutorial is long so here are some jump codes for your convenience
