Learn JSON with online courses and programs
What is JSON?
Consider a typical online shopping experience. As the user, you purchase a specific item at a specific price on a specific date. Those individual data points are stored as key/value pairs within the website database. In both storage and retrieval, JSON facilitates the interaction between the database and the website itself. The website may use this information to personalize marketing assets or to remind you of your most recent transaction on future purchases.

What is covered in a JSON tutorial?
JSON can be part of a coding curriculum that focuses on back-end or full-stack programming. These courses may introduce a new language such as JSON by explaining its usage and basic structure. They may move on to explaining file syntax and how JSON interacts with other programming languages. A coding boot camp can cover these topics while giving learners opportunities for hands-on experience with JSON.
Some courses may be specific to learning JSON. Curricula can provide an overview of how to create JSON objects and structures and how to use JSON for interface testing. It may also cover structured data as a concept, the core approaches used to structure data, and how JSON compares to other data interchange formats.
Jobs that use JSON
Because JSON is primarily used to handle website data, professionals working in web development use JSON in their day-to-day work. In almost all cases, JSON is used for the purpose of exchanging data between applications. These roles span several areas of software and web development.
Some of the jobs that use JSON include:
Compared to XML and other data interchange formats, JSON is much easier for humans to write and understand. It’s also specifically designed for use as a data interchange format, whereas XML was originally a markup language. For these reasons, many web developers use JSON for data interchange purposes, whether they’re building e-commerce sites or social networks.Footnote 3
How to use JSON as a software engineer
As a software engineer working in front-end development or back-end development, you may encounter JSON often. Familiarity with JSON syntax can be crucial for web developers. Websites are rarely static. JSON allows you to populate fields with information specific to a user, time of day, location, or other variable factor.
