Check if array contains object-only-element in Javascript -

i want check if array contains only objects. created function:

function arraycontainsobjonly(arr){   return arr.join("").replace(/\[object object\]/g, "") === ""; } 

here how use it:

// return true arraycontainsobjonly([   {"name" : "juan", "age" : 28},   {"name" : "pedro", "age" : 25} ]);  // return false arraycontainsobjonly([   {"name" : "juan", "age" : 28},   "name=pedro;age=25" ]); 

is there cleaner way this? using literal "[object object]" checking safe? prefer non-jquery solution.

conceptually simpler , cleaner, no less code:

function arrcontainsobjonly(arr) {   return arr.every(function(el) {     return object.prototype.tostring.call(el) === '[object object]';   }); } 

update

on second thought, variant better, return false on encountering first non-object:

function arrcontainsobjonly(arr) {   return !arr.some(function(el) {     return object.prototype.tostring.call(el) !== '[object object]';   }); }
