I got the Wrox.Beginning.JavaScript.3rd.Edition and wanted to start learning it from scratch, then my boss came along and said that why bother, learn jQuery. Can I understand jQ
Maybe your boss is trying to save you some time learning the basics of Javascript and start you off learning jQuery right away but I think this would be a bad idea.
Understanding the basics of javascript is key to using jQuery successfully. jQuery provides shortcuts and solutions to problems (cross browser problems etc) but it is not a language unto it's self.
My advice, learn javascript, learn about handling events in different browsers, inserting in to the DOM and then start using jQuery. You will appreciate it a lot more and be a better coder for it.
