JSON Syntax
A syntax of JSON is similar to JavaScript objects, but still, JSON has some differences.
Rules for writing JSON syntax
Following are the rules for writing JSON syntax-
- JSON data starts with the opening braces({) and ends with the closing braces(}).
- JSON is the collection of key and value pair separated by the comma.
- Key and value are separated by the colon (:). Key is placed on the left side of a colon and value is put on the right side of a colon.
- Square brackets are used to store JSON array.
- Curly brackets are used to hold JSON objects.
- JSON key must be a string and must be enclosed in double quotes. If you try to enclose it in single quotes, you will get an error.
- If the data type of value is a string, then you must enclose it in double quotes.
