Performance Efficient JavaScript

Performance Efficient JavaScript
In pursuit of easiness, familiarity & eye-candy, we often give up or forget to prioritize performance. The ever increasing processing power of devices encourages us to write bloated codes and still be passable. Our apps and websites could suck less, if we care for it a little. May it be bandwidth consumption, underoptimized routines, user experience gotchas or else - knowing what makes JavaScript work better across platforms helps create a better web for everyone. BONUS: it makes you a better programmer!
