FAQ
Why use JSON?
JSON is widely preferred for web APIs, config files, and data storage due to its lightweight structure and readability.
What is Minify and why use it?
Minify reduces JSON dimensions by removing unnecessary whitespace and line breaks. This ensures faster data transfer and less bandwidth usage.
What is the difference between JSON and XML?
JSON is lighter, more readable, and better suited for modern web applications. XML is more verbose but suitable for more complex data structures.
