Password Generator App with Vanilla JS

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

I am proud of creating a working password generator, it still needs improvement in determining the password strength.

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

The biggest challenge was customizing the range slider. I found a helpful article https://blog.logrocket.com/creating-custom-css-range-slider-javascript-upgrades/

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

Any feedback in general, especially in Javascript.
