What is JSON? JSON stands for JavaScript Object Notation
JSON is language independent * JSON is a lightweight data-interchange format
JSON Syntax JavaScript object notation syntax: Data is in
name/value pairs "firstName":“Laurence" Data is separated by commas “firstName":“Laurence", "lastName":“Vandeyar" Curly braces hold objects {"firstName":“Laurence", "lastName":“Vandeyar"}
JSON Syntax (cont.) Square brackets hold arrays [
{"firstName":“Laurence", "lastName":“Vandeyar"}, {"firstName":“Michael", "lastName":“Pereira"}, {"firstName":“Kenneth", "lastName":“Tamsberg"} ] Complete JSON Object Array {"employees":[ {"firstName":“Laurence", "lastName":“Vandeyar"}, {"firstName":“Michael", "lastName":“Pereira"}, {"firstName":“Kenneth", "lastName":“Tamsberg"} ]}
JSON Values JSON values can be: A number (integer
or floating point) A string (in double quotes) A Boolean (true or false) An array (in square brackets) An object (in curly braces) null
