What is JSON?
How JSON works:
Importance of JSON:
Because of the popularity and ease of social media, many sites rely on the content provided by sites such as Twitter, Flickr, and others. With the rise of AJAX-powered sites, it’s becoming more and more important for sites to be able to upload data quickly and asynchronously, or in the background without delaying page rendering. Switching up the contents of a certain element within our layouts without requiring a page refresh adds a “wow” factor to our applications, not to mention the added convenience for our users.
Advantages of JSON:
JSON syntax is very friendly to handle. We have to use only as a syntax which provides us an easy parsing of the data and faster transformation of the data. Since its command is very small and light weighted that’s the reason that it creates response in quick manner.On the server side, parsing is the important part that developers want if the parsing will be fast on server then the only user can get the quick response of their request so in this case JSON server-side parsing is the positive point that indicates us to use the JSON on the server.JSON is the best format for engaging data of any size even audio, video etc. This is because JSON stores the data in the arrays so data transmission makes easier. For this reason, JSON is a great file format for web development and web APIs.
Disadvantages of JSON:
First and foremost, in JSON has no error handling for JSON calls. If the dynamic script insertion works, you get called and will get the response perfectly.If not inserted, nothing happens. It just fails silently. For example, you are not able to catch a 404 error from the server, Nor can you cancel or restart the request. You can, however, timeout after waiting a reasonable amount of time.Another major drawback of JSON is that it can be quite dangerous if used with untrusted services or untrusted browsers, because a JSON service returns a JSON response wrapped in a function call, which will be executed by the browser if it will be used with untrusted browser it can be hacked, this makes the hosting Web Application Vulnerable to a variety of attacks.If you are interested to use JSON services, it’s very important to be aware of the threats which JSON have in that and also be aware of the points which can protect it. JSON only have limited supported tools which we can apply during JSON development.Now a days, several online tools like JSON parser, JSON viewer, JSON validator, JSON formatter etc are available, so developer can easily use all these JSON supporting tools to make development faster.
Some Important Database Management systems that supports JSON are :
As we go through many technologies here we come to end with some positive and some negative parts about JSON. It also have its advantages and disadvantage, like if you desire a quick and perfect result from the server then you can apply it, it has the wide range of schema assist within that but to implement this, the services should be on the trusted network.
