I continue to be fascinated by the language and programming as a whole, so passion has not ebbed. Time, however, is the challenge. Perhaps that's an excuse (if you're passionate enough about something, you'll find a way), but with running BCS Interactive, spending time with two young daughters and precious few moments with their mother, it's been an uphill battle to actually sit down and focus.
That being said, to date I've learned about some of the core principles of .js, specifically:
The DOM - a critically important aspect of development for anyone looking to learn code
Variables - seemed pretty straightforward to me
Onmouse events - I was as giddy as a child when I first did this - knowing full well that it's totally antiquated and often better handled via CSS
Operators - performed some basic mathematical calculations
I even learned to concatenate strings. Just saying that makes me feel like a Nobel-Prize winner. It's a pretty simple aspect of the language and yet remembering the proper structure of putting two strings together requires me doing it over and over.
