Numerous developers use JSON to pass AJAX upgrades between the customer and the server.

Sites upgrading live games scores can be considered as a sample of AJAX. On the off chance that these scores must be upgraded on the site, then they must be put away on the server so that the page can recover the score when it is required.

This is the place we can make utilization of JSON designed information.
