I'm having trouble practicing JavaScript

Hi everyone I just started learning Javascript and I don't have any background in computer sciences, I learned html and css and I didn't have problems with them. Now I started a course on JS and I don't have problem with lectures but when it comes to practice I get clueless, like I open VS code, I create a js file and I stop and look at the empty screen I forget everything and don't know what to type or how to practice it's like my brain is completely empty. It makes me so frustrated and I try so hard not to call myself an idiot or quit learning. What should I do? Is it me or everyone is like this at the beginning?
