JSON

JSON is widely used in web APIs, configuration files and application data exchange because it is compact and supported across programming languages. In practical terms, JSON belongs to the browser, server or document layer. Knowing that layer is important because it tells you what the term can change, what it cannot change, and where to look when something behaves unexpectedly.

The common mistake is to use JSON as if it also meant XML. That blurs two separate decisions and usually sends troubleshooting in the wrong direction. A better test is practical: Validate syntax and confirm that the consumer expects the same property names and data types.

In day-to-day work, JSON matters when structured data must be exchanged in a text format. The practical value is not the vocabulary itself; it is being able to identify the right control, file, setting or decision when the concept becomes relevant.

{"name":"Wemaxa","active":true} is JSON: keys and string values are quoted, and data is represented with objects, arrays and primitive values. That example is useful because it turns the definition into something you can recognize, test and discuss with other people working on the same project.

Use these references when you need documentation-level detail, specifications or product-specific behavior beyond the plain-English explanation above.
