The Good Stuff
It’s Dynamic
It’s Everywhere
It’s Stable (more or less)
It’s Extensible
It’s Been Around a Long Time (in web terms)
It’s not that bad. Really. ;)

Set your ExpectationsAppropriately

This car is good for hauling big things, but doesn’t get great gas mileage.

This car gets great gas mileage, but you can’t (or shouldn’t) move a sofa with it.

If you try to use anything to do something for which it’s not designed for, you will get sub-optimal results.

Fear & Loathing in JavaScript
What to watch out for:
True and False vs. “Truthy and Falsy”
Strict operators: === and !==
Type strangeness
It’s not a strongly typed, language get over it
Maybe that’s a good thing
Lack of strong typing === greater flexibility
When Typos Attack
Bottom line:
Embrace and Enjoy JavaScript for what it is.
If you expect JavaScript behave like a strongly typed language, then you will be sorely disappointed.

Great Book
Excellent book to read when approaching JavaScript with a skeptical eye.
