I really love the focus on the core functionality & concepts being taught, and getting the app to work based on this. I don't have to comb through thousands of e.g. CSS styling videos or other things not important (at the point of learning). Also simple and straightforward, like the previous short google spreadsheet course here: https://www.udemy.com/course/spreadsheet-json-ajax It builds upon the previous short course to help understand another use case example. Very helpful course. Thank you! Extra Note: It would be nice though to at least include a portion that shows practical example of how it works in a production app, not only localhost.

a little difficult to understand as a beginner, maybe you should learn from the basics first

On the the 2nd video, and am learning so far. Though my comment is hope that the instructor talks more slowly. Other than that, superb and wanted to finish this course

By Sébastien Deseille on 3/6/2021
