Agreed. 

I had a brief tussle with JavaScript and gave up on it because:

1) I like strongly typed languages because I appreciate the compile-time 
error checking that these languages support. At the time I tried it, 
JavaScript seemed to have a policy of leaving all error detection until 
the flawed statement was actually executed. Of course, this has major 
implications for unit test coverage, but somehow I doubt that this is 
widely understood.

Even awk, a traditional UNIX scripting language with a compile-and-go 
style of runtime interpreter has always been much better at error 
detection than JavaScript was in my experience.

2) I learn languages best by reading books but I was utterly unable to 
find even a barely adequate book on JavaScript. The O'Reilly book I 
eventually ended up with was one of their worst, little more than a 
recipe book for JavaScript fragments. It had no satisfactory description 
of the language constructs and syntax. Even comp.lang.javascript was 
unable to suggest a good book.
