JSON is a means of representing information that is very simple to understand for web applications and is used for web applications to present information to the users in a manner that will be easily translated by the application. A table of the latest bets that someone is allowed to make on a betting site or a sporting website, for instance, can make use of JSON to transfer the users bet from their web browser to the application that receives the placed bet and saves it to be able to pay out the returns at the very end of the game. This makes for real-time systems that are able to provide live responses to their users and are very simple to operate.
In the past, XML was greatly used as a markup language for objects that were transferred to the web from the web browser. However, it was heavy and very inefficient and cannot be used for modern web applications that are fast and are in great demand which means they cannot afford to be slow or unresponsive for the users. JSON is an upgrade over the traditional XML and has made it possible for web developers to have simple means of presenting information that has a greater impact on the users and more useful for organizing information.
JSON also works miracles for mobile applications that interact with back ends that are made up of massive applications. The mobile applications will mostly receive input from the user in the form of actual input or simple choices that are made from the list provided. This information gets summarized down into the JSON and transferred from the mobile application to the server and processed or even stored. Games that are played on mobile, for instance, keep the server updated on the gamers progress through the JSON and are considered to be really efficient for the applications that are used in modern days.
In brief, JSON is a modern means of information representation that is much lightweight and makes moving data from web applications and mobile applications cheaper and easier for the applications to translate and make sense out of it. It has been known to be really effective in keeping simple information moving from an application to the server and makes for really efficient modern applications that meet the standards for information representation and transfer in real-time.
