I read this article Unobtrusive JavaScript with jQuery and I noticed these points in the slide page 11
- some companies strip JavaScript at the firewall
- some run the NoScript Firefox extension to protect themselves from common XSS and CSRF attacks
- many mobile devices ignore JavaScript entirely
- screen readers do execute JavaScript but accessibility issues mean you may not want them to
I did not understand the fourth point. What does it mean?
I need your comment and responses on these points. Is not using JavaScript and switching to libraries like jQuery worth it?
UPDATE 1 :
whats the meaning of Unobtrusive JavaScript with jQuery ? and yes it does not say we should use libraries but we should have them on external files for that reason i asked my question.
