My law "When you don't know what you are doing sit back read and then code."

Most of the people start writing JavaScript without learning it( ridicules!). Like much of the language JavaScript also has good and bad parts. If you start doing something without learning it you will end up writing something non-standard or bad practices.

JavaScript despite having few bad parts its has some extra ordinary good parts which makes the language cool, beautiful, elegant, highly expressive language. So, to be a better programmer in JavaScript learn the good things, know the bad things and code the good things avoiding the bad part. Its very important to learn good things when you learn a language because its hard to unlearn the bad things.

Why JavaScript?

JavaScript is THE language of web browser, sun came up java applet gave a try to override JavaScript ended in a failure. Applet is just crap(You are a java lover you will find hard time reading my blog because I bash Java a lot :) and you thing java and JavaScript are one and the same I am gonna kick your ass get lost. Let me write about the name history behind JavaScript in a another post.). I call JavaScript as THE language because you don't have any other option. I see JavaScript is often blamed for browser hang probably because of you are doing extensive DOM operation. This is not the fault with JavaScript, DOM API very awful and JavaScript is unfairly blamed.

Good and Bad:

Good parts of JavaScript are loose typing, dynamic object, include functions and very bad part of JavaScript is using global variables. Some of the other good parts are lexical scoping, lambda(these is not unique, it resembles more of lisp). JavaScript is object oriented and class free. So inheritance happens between objects. Most of them who are from a strong typed languages feel bit hard to get used to it. People ask how would you identify a variable's type. I learned programming using Lisp, Python so I am much used to it and trust it is a good.
