Frequently Asked Questions
What is JSON used for?
JSON is commonly used for transmitting data between a server and web application, as an alternative to XML. It’s also used for configuration files and data storage.
What are common JSON formatting errors?
Common errors include: missing commas between items, trailing commas, unquoted property names, single quotes instead of double quotes, and mismatched brackets.
Why minify JSON?
Minification reduces file size by removing unnecessary whitespace, which improves transmission speed and reduces bandwidth usage, especially important for web APIs.
What’s the difference between JSON and JavaScript objects?
JSON is a text format that follows strict syntax rules (all keys in quotes, no functions). JavaScript objects are language constructs that can contain functions and use various key formats.
