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

I've been spending most of my time writing code on react or Next.js, I thought to brush on my javascript skills, therefore took this challenge to test my javascript, I was really headache to manage the states in vanilla js as compared to modern frameworks. It was challenging, intuitive & a little bit difficult.
