Bear is spot on
I just want to add that learning any programming (in your list javascript is the most complex language to me) will benefit you by understanding basics of how programming works.
Just simple idea's like closing tags and how to structure code,using comments, etc.
I came from a web developer background and it helped me very little. I feel that php, css, html are extremely easy to learn and if that helps you feel more comfortable to tackle more complex languages then dive in but if your end goal is to create native applications then start with
java (java and javascript are not the same).
Good Luck!
