It turns out my answer is similar to  Anonymous  but I keep my answer here since it explains how I got my answer    The original object has THREE properties  i e  3 keys and 3 values   This suggest we should be using Object keys   to transform it to an array with 3 values   var dataArray   Object keys dataObject      Gives    object1    object2    object3      We now have 3 values  but not the 3 values we re after  So  this suggest we should use Array prototype map     var dataArray   Object keys dataObject  map function e    return dataObject e           Gives     id  1  name   Fred     id  2  name   Wilma     id  3  name   Pebbles
