Difference between JSON.stringify and JSON.parse
JSON.stringify turns a JavaScript object into JSON text and stores that JSON text in a string, eg:
var my_object = { key_1: "some text", key_2: true, key_3: 5 };var object_as_string = JSON.stringify(my_object); // "{"key_1":"some text","key_2":true,"key_3":5}" typeof(object_as_string); // "string" JSON.parse turns a string of JSON text into a JavaScript object, eg:
var object_as_string_as_object = JSON.parse(object_as_string); // {key_1: "some text", key_2: true, key_3: 5} typeof(object_as_string_as_object); // "object"
JSON.parse() is for "parsing" something that was received as JSON.JSON.stringify() is to create a JSON string out of an object/array.
They are the inverse of each other. JSON.stringify() serializes a JS object into a JSON string, whereas JSON.parse() will deserialize a JSON string into a JS object.
