Facebook Live Commenting [New Features]

Facebook live commentingWe spend time on Facebook to check out what our friends are doing. Watching photos and commenting on them. Things get interesting when people suddenly start commenting in large group, but what the hell, I need to refresh my page to see what the new comment is and wait for page reloads.

A terrible mess!

Facebook Engineering team is rolling out a new feature called Live Commenting It's like chatting on your instant messenger, no more page reloads. Just comment auto-loads behind the scenes.

When someone comments on your post or photo, the comments start loading automatically, without any page refresh! This is the magic of Javascript technology AJAX.

To achieve this the facebook team has tested, many  technology approaches like:

  • Pushing vs. Polling Data
  • Write Locally, Read Globally

To understand the details of these processes, you can visit Facebook's Engineering team page.
