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.

{
	"key_1":value_1,
	"key_2":value_2,
	"key_3":value_3,
	.....
	.....
	"key_n":value_n
}
