The purpose and application of hash (#) in URL

Question

I was wondering if there are other uses for hashes besides being an anchor in a URL? I read about it here Get the full URL including the hashed query string. What is the client's status information? please help.

Answer 1

Hashes can also be used in single-page applications, so not only can you use it to navigate to a point in a page, you can also use hashes as a means of navigating from one page to another. The advantage of this is that there is no need to refresh the page.

There is also a method called hash collision, which is used in single page applications to help ajax applications be easier to index.
