Github: https://github.com/lydiahallie/javascript-questions
This is a really good Github repository called "javascript questions". The author publishes weekly questions related to JavaScript. Although they are not difficult, they test the details. After practicing for a while, I realized that I made mistakes on some simple questions because I didn't think about the details properly.
Quoting the author: I post multiple-choice JavaScript questions on my Instagram every day, and I also post them in this repository.
From basics to advanced, test your knowledge of JavaScript, refresh your knowledge, or help you with coding interviews!
