I decided to use the json2 library and I got an error about “cyclic data structures”.

I got it solved by telling json2 how to convert my complex object. Not only it works now but also I have included only the fields I need. Here is how I did it:

OBJ.prototype.toJSON = function (key) {
       var returnObj = new Object();
       returnObj.devid = this.devid;
       returnObj.name = this.name;
       returnObj.speed = this.speed;
       returnObj.status = this.status;
       return returnObj;
   }

I made it that way   if I have   var jsonArg1   new Object        jsonArg1 name    calc this       jsonArg1 value   3 1415  var jsonArg2   new Object        jsonArg2 name    calc this again       jsonArg2 value   2 73   var pluginArrayArg   new Array        pluginArrayArg push jsonArg1       pluginArrayArg push jsonArg2     to convert pluginArrayArg  which is pure javascript array  into JSON array   var jsonArray   JSON parse JSON stringify pluginArrayArg

The shortest way I know to generate valid json from array of integers is let json       cars     for more general object array use JSON stringify cars   for object with circular references use this   x000D   x000D  let cars    1 2 3   cars push 4 5 6    let json       cars      console log json   console log JSON parse json       json validation x000D   x000D   x000D

If you have only 1 object like the one you asked  the following will work   var x      a   b     var b  JSON stringify x   var c   b substring 1 b length-1   JSON parse c

Or try defining the array as an object   var cars        Then there is no need to convert to json  This might not be practical in your example but worked well for me
