How does showComments and isLiked working without any function

I don't understand in the click event of buttons he used isLiked = !isLiked and showComments = !showComments. I don't understand where does the functions lie for these to get called? how does this work?

I'm waiting for an answer on this too. I'm using IntelliJ to code this and it even says isLiked and showComments are unresolved variables but the code still works.

I am not sure, but I think when "isLiked" is defined it is automatically false. And then when you click the button it says make "isLiked" the opposite of what it is (!isLiked) so "isLiked" become true. The CSS will generate when the "isLiked" is true. So if you push the button again it makes "isLiked" the opposite again, which is false and the CSS will be removed.

Hey Ken Howard

Could you Lokesh would like some explainer on this? Could you write a few details on this?
