What JSON means
It is easy for people to read and for programs to parse in almost any language, not only JavaScript.
JSON-LD, a JSON-based format, is how websites add structured data for search engines.

JSONJavaScript Object Notation
JSON is a lightweight text format for structured data, written as keys and values. It is the standard format APIs use to exchange data.
Example
An API returns a course as {"title": "Web Development Course", "modules": 7}, which the website turns into a page.
Why it matters
JSON is everywhere in modern web work, from APIs to configuration files to SEO markup.
