Json.parse () and Json.stringify ()

The Json.parse () and Json.stringify () methods inside JavaScript:

1.parse is used to parse a JSON object from a string. For example

var str= ' {' name ': ' CPF ', ' age ': ' 23 '} '

The JSON object is obtained by Json.parse (str):

[Object Object];

Object:age: "23"

Name: "CPF"

_proto_:object

PS: Single quotes are written outside {}, each attribute must be double-quoted, otherwise an exception will be thrown

2.stringify is used to parse out a string from a JSON object, such as

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

Obtained by Json.stringify (a):

"{' A ': 1, ' B ': 2}" "
