Okay , I already have programming fundamentals(did a bit of csharp and very basic java …). But iam really interested in website development. Html and CSS and photoshop are what i best know on this planet lol. Today i had a look at a very fancy javascript image slide show code, 14000 characters long it was,i could not even try to read that… customized error alert like during form filling are also very long. I think it would be hard to code that without glancing anywhere.(I know how to validate most fields with default browser prompt.) Do people code that?? Or just copy from i dont know libraries or online free source codes? Cause if I could have copied that others may. I also need tips …like what to more focus on…thank you ---

Knowing CSharp and Java help, but JavaScript has its own set of concepts that don’t map well to other languages. The biggest areas are relating to the DOM. I would suggest you take an hour or so and go through the material under “The DOM” here: [https://www.kirupa.com/javascript/learn\_javascript.htm](https://www.kirupa.com/javascript/learn_javascript.htm) Cheers, Kirupa 😛
