Materials on modern Javascript?

Question

JavaScript

The time has come for me to take up client-side scripting, but I am superficially familiar with Javascript. In this regard, the following materials are needed:

• Frequently used libraries (if there is something like Perl's CPAN, it's generally great)
  
• Language guide
  
• Code examples - to understand how they write it now
  
• AJAX application
  
• And finally, the question is: is cross-browser scripting still a problem, or has it been successfully solved?
  

Answer 1

cross-browser issues are usually encapsulated in libraries/frameworks (jQuery/Prototype/Mootools/etc) and rarely come up.

Answer 2

1. jQuery, MooTools, Prototype, etc.
2., 3., 4. javascript.ru/
5. To be decided by the developer.

Answer 3

Next door is a similar topic - habrahabr.ru/qa/2531/

Answer 4

I actively use w3schools.com/ as a Javascript reference (without affecting frameworks) , it is also very useful in HTML, CSS. For the last two , reference.sitepoint.com/ is no less interesting, as it reveals several other aspects.
I mainly use JQuery as a framework. On it, I can name the following materials as useful:
anton.shevchuk.name/javascript/jquery-for-beginners/
docs.jquery.com/Main_Page
docs.jquery.com/Tutorials
It is also quite harmless to get acquainted with debugging in Firebug. On Habré ran a very good series of articles about him.

Answer 5

Answer 6

Take Javascript lessons at an intermediate level and study, write your own projects in parallel to hone your skills.
