Upon first appearance  the word  merg  leads one to think you need to use  extend  which is the proper jQuery way to  merge  JSON objects   However    extend true      json1  json2   will cause all values sharing the same key name to be overridden by the latest supplied in the params   As review of your question shows  this is undesired   What you seek is a simple javascript function known as  concat   Which would work like   var finalObj   json1 concat json2     While this is not a native jQuery function  you could easily add it to the jQuery library for simple future use as follows     function          if     concat              extend               concat  function                     return Array prototype concat apply     arguments                                      jQuery     And then recall it as desired like   var finalObj     concat json1  json2     You can also use it for multiple array objects of this type with a like   var finalObj     concat json1  json2  json3  json4  json5           And if you really want it jQuery style and very short and sweet  aka minified     function a  a concat  a extend  concat function   return Array prototype concat apply    arguments        jQuery      x000D   x000D    function      concat    extend  concat function   return Array prototype concat apply    arguments        jQuery   x000D   x000D    function     x000D      var json1     id 1  name   xxx     x000D          json2     id 2  name   xyz     x000D          json3     id 3  name   xyy     x000D          json4     id 4  name   xzy     x000D          json5     id 5  name   zxy     x000D       x000D      console log Array 10  join  -     json1  json2  json3   Array 10  join  -     x000D      console log   concat json1  json2  json3    x000D      console log Array 10  join  -     json1  json2  json3  json4  json5   Array 10  join  -     x000D      console log   concat json1  json2  json3  json4  json5    x000D      console log Array 10  join  -     json4  json1  json2  json5   Array 10  join  -     x000D      console log   concat json4  json1  json2  json5    x000D      x000D  center   padding  3em    x000D   lt script src  https   ajax googleapis com ajax libs jquery 1 9 1 jquery min js  gt  lt  script gt  x000D   lt center gt See Console Log lt  center gt  x000D   x000D   x000D    jsFiddle
