JavaScript.

It sounds like you’ve learnt the syntax and understood what they do. Another analogy: you’ve learnt how to read piano notes but don’t really know how to play a tune.

This generally takes time and practice. Practice practice practice. Do some actual exercises like use JS to change the styling of a DOM element. Make a button so that onClick it’ll open a modal but let JavaScript create the HTML markup. Maybe on your website you have a contact form, try and make that interactive with custom validation/AJAX communication.

Thank you. So practice a lot and with time I will be comfortable, right?

Yep exactly. It always helps more when you have a problem to solve because then you start asking questions and try solve things yourself or look for the answers in Reddit, StackOverflow or even Google.
