Frequently Asked Questions
Is JSON the same as JavaScript?
No. JSON was inspired by JavaScript object notation, but it's a standalone data format used by virtually every programming language. It's simply a way to structure data using key-value pairs, arrays, and nested objects.
Where is JSON used on websites?
Everywhere behind the scenes. API responses, configuration files, structured data for SEO (JSON-LD), CMS data storage, and communication between your browser and web server all commonly use JSON format.
Do I need to understand JSON?
As a business owner, no. But if you ever look at API documentation, structured data markup, or your CMS configuration, you'll see JSON. It's human-readable, so you can usually understand the gist even without technical knowledge.
