Here is a good JSON.stringify() example code in JavaScript.

<!-- JSON-stringify.html
     Copyright (c) FYIcenter.com

<html>
<body>
<script type="text/javascript">
   var str1 = JSON.stringify(2020);            // A number value
   var str2 = JSON.stringify("foo");           // A string value
   var str3 = JSON.stringify(true);            // A Boolean value
   var str4 = JSON.stringify(null);            // A null
   var str5 = JSON.stringify([1, 5, "false"]); // An array
   var str6 = JSON.stringify({});              // An empty Object
   var str7 = JSON.stringify({"msg": "Hi!"});  // An Object

   document.write("<p>String from JSON.stringify():</p>");
   document.write("<pre>");
   document.write("   str1 = "+str1+"\n");
   document.write("   str2 = "+str2+"\n");
   document.write("   str3 = "+str3+"\n");
   document.write("   str4 = "+str4+"\n");
   document.write("   str5 = "+str5+"\n");
   document.write("   str6 = "+str6+"\n");
   document.write("   str7 = "+str7+"\n");
   document.write("</pre>");
</script>
</body>
</html>

Save the above code in a file, JSON-stringify.html, and open it in a Web browser. You see the following output:

String from JSON.stringify():

   str1 = 2020
   str2 = "foo"
   str3 = true
   str4 = null
   str5 = [1,5,"false"]
   str6 = {}
   str7 = {"msg":"Hi!"}
