This topic  especially the answer of Xotic750 was very helpful to me  I wanted to generate a json variable to pass it to a php script using ajax  My values were stored into two arrays  and i wanted them in json format  This is a generic example   valArray1    121  324  42  31   valArray2    232  131  443   myJson    objArray1      objArray2       for  var k   1  k  lt  valArray1 length  k          var objName    obj    k      var objValue   valArray1 k       myJson objArray1 objName    objValue    for  var k   1  k  lt  valArray2 length  k          var objName    obj    k      var objValue   valArray2 k       myJson objArray2 objName    objValue    console log JSON stringify myJson      The result in the console Log should be something like this         objArray1              obj1   121           obj2   324           obj3   42           obj4   31           objArray2              obj1   232           obj2   131           obj3   443
