What Is Object Oriented Javascript & Gwt? javascript and gwt

Hi all,What z actually object oriented concepts using javascript.How can i learn that?.I know something in basic javascript.And one other thing is how can i learn gwt.(Google web Toolkit)?..what are the prerequisites to learn GWT???

Object Oriented just means you treat every entity in your code as objects. They have properties and methods (actions) you can perform on them to do various tasks.The GWT I remember is a toolkit to allow you to write web applications that uses a lot of JavaScript in Java so you will need to know a fair bit about java. Its purpose to allow you to write complex applications without worrying about cross browser compatibility issues. I have tried this before but not to the level of producing anything. To me it seem like a lot of over head before you got anything working and in the end when I wanted to change something small like the layout or style of something it wasn't so obvious where.
