Hoping for new courses to be available soon. so, I can learn more.
some time the code is executing slowly and the sandbox controls not work, is necessary to give a page refresh

Loved this way of learning, plus course outline is well organized
Good course, similar to freeCodeCamp one but nice!!
To print it to the console is too slow. When you are doing the exercise and you didn't do it well the Run button it gets stuck and I have to refresh the website every time I have a mistake, so I can re-write my code.
Please complete the Course first and then work on Projects.
