metode filter 2 array yang efektif
array a = ['a','b','c'] array b = ['a','c']
result = ['b']
apakah ada cara efisiennya untuk mencari array yang berbeda diantara 2 array tersebut?

coba pakai array_diff() contoh:
<?php $a1=array("a"=>"red","b"=>"green","c"=>"blue","d"=>"yellow"); $a2=array("e"=>"red","f"=>"green","g"=>"blue");
$result=array_diff($a1,$a2); print_r($result); // hasil print : Array ( [d] => yellow ) ?>

kalau di javascript bentuknya begini :
array_diff(['Kevin', 'van', 'Zonneveld'], ['van', 'Zonneveld']) //hasil Kevin

let difference = arr1.filter(x => !arr2.includes(x));
