40% of it just keeps droning on about how noobs will fall for these traps, and saying things like "If you are new to JavaScript, I suggest avoiding the this keyword".. as if these concepts are so mind blowing noobs minds will melt.
it does bring up a few good points but it could have been a lot shorter.. and how is closure a common js gotcha? the list includes 4 javascript constructs veiled into a rant.
But from my experience, someone who is coming into JS for the first time is probably not setting up a complicated object hierarchy - they're probably just trying to figure out how to bind some events to a DOM element and get some basic UI functionality. And they probably don't need to use the this keyword as much as they think they have to.
I completely agree that this could be a bad decision on my part, or at least a very controversial one. But I'd rather have truly new JavaScript developers focus on things like encapsulation and closures before they get too far into the this keyword and constructor/prototype.
