HTML, CSS, Javascript, BEM naming convention

What are you most proud of, and what would you do differently next time?

The animation for the hamburger menu looks great. I'm also happy with how the backed amount animation start increasing after a pledge was placed. Next time I will make an overview screen where you can see what pledge you will place after you click continue. In Javascript are some pieces of code repeated because I didn't think of a solution how I didn't have to repeat the code. Later on I had to change something and needed to change it at different places in my code. Hopefully I could change that in the future.

What challenges did you encounter, and how did you overcome them?

I had trouble with the animation for the backed amount, process bar and total backers. First they run at the same time and it was not looking good. I tried to make a callback function for it but it needs still improvement. For the days counter I searched on YouTube for a tutorial and found a good js library for it.

What specific areas of your project would you like help with?

I'm very curious if I implemented the BEM naming convention right. Do you have any feedback for improving the animation for the backers amount, progress bar and total backers. Is there a better way to organise my Javascript code so that I don't repeat too much code?
