 var device_array = { device_id : [["7547092d-e03e-5148-a54f-8276a85d7f70","cpp_node_192-168-56-1:6111"]] }; var from_file_array = [ { device_id_from_file: "7547092d-e03e-5148-a54f-8276a85d7f70" }, { device_id_from_file: "93e71ba7-fb56-5592-a5f6-d855203dd7ae" }, { device_id_from_file: "93e71ba7-fb56-5592-a5f6-d855203dd7ae" }, { device_id_from_file: "fe21abdf-706f-5c7b-adb8-2507e145e820" }, ]; var val = device_array['device_id'][0][0]; for (var i= 0; i < from_file_array.length; i++) { if(from_file_array[i].device_id_from_file === val){ console.log("device ids are matches"); }; };

try this,you just want the which file data is matched right?

from_file_array.filter(each=>each.device_id_from_file===device_array.device_id[0][0])

it will give the matched device_id_from_file;if not you will get empty array
