Sun turns JavaScript into Java. Google turns Java into JavaScript

JavaScript is said to be World's Most Misunderstood Programming Language. Why is the language so misunderstood? It may be the name JavaScript ;). It doesn’t have any relation with Java.
No programming language is perfect. JavaScript has many errors like overloading of +, reserved word policies are too rigid, Semicolon insertion and some more.

When I started working on JavaScript, I felt it an easy language but sooner I was facing many issues like browser compatibility, memory leaks and many other common problems.
There are many sites discussing about all these. I would refer few of them in this post.

Being a scripting language, support of object-oriented programming is quite impressive. Even though there are no classes and instances, there are objects, prototypes, and implicit inheritance.
Browser compatibility issue can be handled using object level detection (Don’t check browsers rather check objects).
Memory leak is a challenging problem. The browsers try to work well with broken web, making it look fine and behave well. This is a very difficult task. If browser fails to collect the garbage that we left, is a buggy browser (memory leak). Most browsers don't do a very good job about memory leak.

I would like to say thanks to Google and many other companies which are writing JavaScript libraries and making JavaScript hot. A good JavaScript Compiler would definitely make JavaScript library implementation easier. Check Google’s web development toolkit.
Mozilla's (Venkman) JavaScript engine has built-in support for debugging, and thus can provide powerful tools for JavaScript developers.
