When I noticed that I would have to reference Web colours in RGB hex code, I was glad I was already very familiar with hexadecimal code.
I greeted the discovery of external scripts for JS and CSS with joy, because I knew how versatile those external scripts could become; I only needed to code one particular style or JavaScript function or object once, in one file, and use that code throughout the site; maintenance would be a breeze, too, because I'd only have to update a given style or JS function, again, in one place.
So, to summarise, my first thought on becoming acquainted with HTML, CSS and JS was "This is going to be so useful."
