To put into practice everything I learned in this course from Jonas Schmedtmann, we created a recipe viewer. It's a project using an API made by Jonas that contains a whole list of recipes. The goal is to put into practice all the sections of the course. I.e. asynchronous code, classes, modules, ES functions and much more!
This is a Javascript based course. I didn't realize the HTML, and CSS part of this project.
I recommend this course and the others by Jonas Schmedtmann.
