Intro component with Sign-Up form

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

I’m mostly proud that I managed to implement every functionality and followed best practices (to the best of my abilities).

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

Because the design doesn't clearly specify whether the text in the field is a placeholder or a label, I decided to make it a label. Since I wanted the label to be visible at all times, I had to use JavaScript to detect changes in the text field's value.

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

Any feedback is appreciated, but I would especially like to know what improvements I can make to my JavaScript code.
