javascript - Concat two arrays But concat is not working -

i have 2 arrays.i want concat both array values.but here shows me error,

newsarr.contact not function

my code

     var globalnews = [];      var commentarray = [];      var commentarr = {};     commentarr['comment'] = comment;     commentarray.push(commentarr);         var newsarr = {};     newsarr['newsno'] = $("#newsnumber").val();     newsarr['desc'] = $("#desc").val();     //globalnews.push(newsarr.concat(commentarray)); // not working     globalnews= newsarr.concat(commentarray); 

you can use $.merge( commentarray, newsarray ); concatenate arrays:

$(document).ready(function() {      var globalnews = [];      var commentarray = [];      var newsarray = [];        var commentarr = {};      commentarr['comment'] = 'aaa';      commentarray.push(commentarr);           var newsarr = {};      newsarr['newsno'] = 'bbb'      newsarr['desc'] = 'vvv';      newsarray.push(newsarr);        globalnews = $.merge( commentarray, newsarray );      console.log(globalnews)  });
