I was recently asked this question by a very smart technical person, and found that I ended up using words like statically typed and dynamically typed that lacked the clearness to allow the user to understand what the differences are. Why would you use one over the other?

They will take anything in their stride. Throw anything at them and they will keep quiet and work with it.

Variables in statically typed langauges ask a lot of questions before you give them anything. And they still throw errors sometimes even if you make a slight mistake. They're very unforgiving. You know, just like the...

when you use the Var in javascript that has just been consumed, I take it the application blows up at runtime?

But I thought it would never blow up at runtime because it is always valid. Just more like incorrect logic giving you unsatisfying result. Have no idea what this would do, var a = 1 * "one";

In dynamic languages, values are usually typed, in static typed languages, variables are usually typed.

I understand that most of the enthusiasm displayed is conspicuous, learned behavior. In other words, developers pretend to be in love with JavaScript just because they see, hear or read other developers pretend to be in love with it, who pretend because they see, hear or read other developers...you get the idea.

Reading and debugging JavaScript code is a serious, unremitting pain in the posterior. I don't understand why this alone shouldn't reduce its popularity with developers.
