javascript - Check if a JSON array is empty -

i know first sounds duplicate question don't think is...

i receiving json array as:

var test1 = [] ; 

or

var test2 = [{},{},{}] ;  //this empty 

i have no problem finding out if test1 empty.

jquery.isemptyobject(test1) 

my problem test2... please note in cases test2 might return like:

var test2 = [{"a":1},{},{}] ;  //all these not empty var test2 = [{},{"a":1},{}] ;  //all these not empty var test2 = [{},{},{"a":1}] ;  //all these not empty 

the above scenarios shouldn't counted empty.i've tried use .length it's not helping length 3... ideas?

cheers.

function isarrayempty(array) {     return array.filter(function(el) {         return !jquery.isemptyobject(el);     }).length === 0; } 

jsfiddle demo

passes of tests.

a pure javascript solution replace !jquery.isemptyobject(el) object.keys(el).length !== 0

edit: using array.prototype.every

function isarrayempty(array) {     return array.every(function(el) {         return jquery.isemptyobject(el);     }); }
