Answer 1

 let c = JSON.stringify({
        "people": [

            { "firstName": "Brett", "lastName": "McLaughlin", "email": "aaaa" },

            { "firstName": "Jason", "lastName": "Hunter", "email": "bbbb" },

            { "firstName": "Elliotte", "lastName": "Harold", "email": "cccc" }

        ]
    })
    console.log(JSON.parse(c))

标准数据类型
