JSON and JavaScript

JavaScript is one of the core technologies of the World Wide Web alongside HTML and CSS. JavaScript brings web pages to life. Without it, modern web design would be static and boring. JavaScript is a programming language. It is probably the most important programming language because every aspect of web development is built off of it. This is why it is a core technology of the World Wide Web.

JSON is short for JavaScript Object Notation. So is JSON JavaScript? Not exactly. JSON is a data format that is independent of any programming language, although it is derived from JavaScript. The bulk of modern programming languages contain code that can generate and parse JSON data.

A few notes on JSON:

  • It is a lightweight format for storing and transporting data

  • The syntax is self-describing, making it easy for humans to read and understand

  • Typically, JSON is used when data is sent from a server to a web page

JavaScript and JSON are two completely different things. While JSON is derived from JavaScript, the two are not exactly comparable in any way. However, we can compare JSON to JavaScript objects. These two are more closely related, and they offer us a better comparison.
