JSON is more concise and readable than XML, and has faster parsing speed. JSON uses key-value pairs to represent data, while XML uses tags. JSON supports arrays natively, while XML requires additional markup. In web development, JSON has gradually replaced XML as the main data interchange format.
The basic syntax rules of JSON include: using key-value pairs to represent data, key names must be in double quotes, strings must be in double quotes, numbers can be integers or floating-point numbers, boolean values are true or false, arrays use square brackets [], objects use curly braces {}, and different items are separated by commas.
