What is JSON?

FAQs

JSON, or JavaScript Object Notation, is a text-based data interchange format that is used for transmitting information between web application clients and servers. JSON is light-weight and enables faster data transport.

JSON is a text-based, light-weight data interchange format used to transmit data from server to client in web applications. It’s a convenient method of data transport because of its similarity to JavaScript objects. A simple example of JSON is: { “countryName” : “Mexico”, “countryCode” : “+52” }

JavaScript is a programming language, whereas JSON is just a data exchange format. JSON does not support functions, whereas JavaScript has many pre-defined as well as user-defined functions. JavaScript has in-built methods to convert objects into JSON strings and vice versa, to enable faster data transfer between web application client and server.

There is a subtle difference between JS and JSON objects. For example, JS objects can have single quotes for name-value pairs, whereas for JSON objects, double quotes are a must. Otherwise, they are equivalent. It’s also easy to convert JS objects to JSON using the stringify() method and vice versa using the parse() method.

JS is the abbreviation for JavaScript and not JSON. JavaScript is a programming language used for building the user interface of a web application, whereas JSON is a data interchange format used for transferring data between front end and back end.

XML is a markup language, while JSON is a data interchange format used by web applications. JSON data is readily available and is human-readable, whereas XML data needs to be parsed. Also, JSON is supported by most browsers, whereas XML parsing can be tough at times. XML is more secure compared to JSON.

Both CSV and JSON are used extensively for storing large volumes of data. Whether JSON or CSV is better depends on the requirements. If you have limited memory available for your data and want a compact format, CSV is a good choice. CSV has a flat structure like SQL tables. If your project demands more flexibility and scalability in terms of adding or editing schema or values, JSON would be a good choice. JSON allows embedded objects inside JSON objects, so all the relevant data can be stored and retrieved from a single view.
