below data after convert into JSON.parse

 {
        "agefrom":18,
        "ageto":60,
        "heightfrom":"1",
        "heightto":"28",
        "steps":"",
        "number":"",
        "education":""
   }

If your first object is your actual object (`obj`) doing `console.log(JSON.parse(JSON.stringify(obj)));` gives back the same object, with the array values - no data is lost from stingifying and then parsing it — Nick Parsons, Mar 10 '19 at 12:58
console.log return correct value, but here I assign that value like let val = JSON.parse(string_data); console.log(val); empty data like second object — Anbuganesh Kannan, Mar 10 '19 at 13:21
