What is JavaScript Object Notation (JSON)?

by Iwan Price-Evans on Web technology • May 19, 2022

JSON stands for JavaScript Object Notation. It is an open standard format used to exchange data between different applications and web services. It was developed by Douglas Crockford as a replacement for XML.

What Does JSON Do?

JSON is a lightweight data-interchange format designed to represent objects and arrays. JSON is easy to read and write because it uses human-readable text instead of binary code.

Why Should I Care About JSON?

JSON is a very common language used to communicate with web services. If you use APIs to access data from other websites, then you will need to understand how JSON works. You should also learn how to parse JSON so you can make sense of the data returned by the API.

Why Use JSON?

JSON is designed to be easy to read and write. It is also very flexible because it allows developers to use any combination of characters to represent values. This makes it ideal for transferring data across multiple platforms.

JSON is often used when developing mobile apps. It is a simple text file format that uses human-readable syntax. It is commonly used with RESTful APIs (application programming interfaces). These APIs allow users to access data through a web browser using HTTP requests.

How Do I Start Using JSON?

If you are new to JSON, there are several online tools available to help you learn more about it. One such tool is JSONLint.com. This website provides a quick overview of how JSON works and what each part does. You can also use Google to search for “JSON tutorial” or “JSON cheat sheet.”
