Noob questiion about adding number to string : I have this line of code:

`($(".contact-msg-inpt").prop("scrollHeight"))`

and I'm trying to figure out how can I add a number, say 5 or 8, or 10 or whatever to this value, but in one line?

I tried this one, but it didn't work:

`parseInt("(($(".contact-msg-inpt").prop("scrollHeight"))", 10)`
