Introduction to the use of JSON.parse() and JSON.stringify()_javascript skills

parse is used to parse a json object from a string, such as

var str = '{"name":"huangxiaojian","age":"23"}'

Result:

JSON.parse(str)

Object

age: "23"
name: "huangxiaojian"
__proto__: Object

Note: Single quotation marks are written outside {}, and each attribute name must use double quotation marks, otherwise an exception will be thrown.

stringify() is used to parse a string from an object, such as

var a = {a:1,b:2}

Result:

JSON.stringify(a)

"{"a":1,"b":2}"
