Avoid Full Page Refresh

[eluser]Kentish[/eluser]
Hello

Am making a website for a photography club.

I need to implement the 'likes' and 'comments' for each photo.

However, i want to avoid a full page refresh when a user likes or comments on a photo.
That is, i want it to be shown in real-time, instead of having to refresh the whole page to reflect the changes.

Any steps/or other language i need to use to do that...?
