The basics of the JavaScript is the same. But there are a lot of additional libraries and frameworks, that use basic JS and extend it in somewhat unexpected manner. The main problem with JS is the libraries. If you are interested in web development then first you should get information about HTML, next about browser model and finally about object model, that is used in JS for working with browser and html objects. Next there is a communication issue. When an application is contained within a browser it is unable to use server side databases and everything else. That's why there are many libraries targeted at the browser to server communication. They use different data formats (XML, JSON, something else) and of course they all are different with different set of capabilities.SeanMc wrote:I obtained a Javascript textbook, but that was back in 2006/7, and the publishing date says (I think) 2003. So it might not have use anymore?
So, to start using JS effectively you need to get a grasp around all those technologies, not only basic JS syntax. And you should remember that the diversity of JS libraries is too inflated and to get rid of not convenient tools it is required to try many of them. But it is the common problem of a complex application development.
