Ajaxian » So you want to write Javascript for a living?

* You need to know how to create an element on the fly, get a reference to any element on the page, insert, remove, replace, etc. nodes in the page. These methods should be memorized!
* No modern web application can survive without event handlers. Knowledge of the differences across browsers and issues surrounding event handling are a must.
* Do you have any experience with JSON? If so, … why do you think some developers may prefer to use this as the envelope language as opposed to XML?
* This means understanding how to set up a prototype chain and how to make sure a base constructor is applied correctly in the process of object instantiation.
* The basics of JS object mutability, and using that to isolate code. Basically faking namespaces by using objects to hold other objects.
* It’s really important for you to be able to write your own code without relying on JavaScript libraries like Dojo, Prototype, etc.
