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

Answer 1

Web Developers use javascript:void(0) because it is the easiest way to prevent the default behavior of a tag. void(*anything*) returns undefined and it is a falsy value. and returning a falsy value is like return false in onclick event of a tag that prevents its default behavior.

So I think javascript:void(0) is the simplest way to prevent the default behavior of a tag.
