json - Using filter with each on lodash -

-

i have json string

[   {     uri : '/someuri/one',     title : 'title 1',     displaylocation : 'action_menu',     masterdata : 'location',     iconclass : 'icon-class-1'   },    {     uri : '/someuri/two',     title : 'title 2',     displaylocation : 'action_menu',     masterdata : 'location',     iconclass : 'icon-class-2'   },   {     uri : '/someuri/three',     title : 'title 3',     displaylocation : 'action_menu',     masterdata : 'job',     iconclass : 'icon-class-3'   },   {     uri : '/someuri/four',     title : 'title 4',     displaylocation : 'summary',     masterdata : 'location',     iconclass : 'icon-class-4'   } ]

i converting to

[   {     iconclass : 'icon-class-1',     id : 'anythingunique',     text : 'title 1'   },    {     iconclass : 'icon-class-2',     id : 'anythingunique',     text : 'title 2'   } ]

using following code

function mycustomfilter(inputjsonstr) {   return _.each(inputjsonstr.filter(function(action){     return action.masterdata === 'location' && action.displaylocation === 'action_menu';   }), function (action) {     return [{iconclass: action.iconclass, id: 'anythingunique', text: action.title}]; });

but returning me json string 

[   {     uri : '/someuri/one',     title : 'title 1',     displaylocation : 'action_menu',     masterdata : 'location',     iconclass : 'icon-class-1'   },   {     uri : '/someuri/two',     title : 'title 2',     displaylocation : 'action_menu',     masterdata : 'location',     iconclass : 'icon-class-2'   } ]

can suggest doing wrong?

you use map this:

_(inputjsonstr).filter({masterdata: 'location', displaylocation: 'action_menu'})      .map(function(a) {          return {iconclass: a.iconclass, id: 'anythingunique', text: a.title};      }).value();

i've changed filter little, way if wanted, , i've used functional approach chaining, imperatively if makes more comfortable. map replaces array element returned element.
