What does “[removed]void(0)” mean?

Question

I\'ve seen such hrefs many times, but I don\'t know what exactly

Answer 1

There is a huge difference in the behaviour of # vs javascript:void(0);.

# scrolls you to the top of the page but javascript:void(0); does not.

This is very important if you are coding dynamic pages because the user does not want to go back to the top when they click a link on the page.
