console.log(filterByReference(arr1, arr2));compare and filter two array of object
array1 = [{path: "hello"}, {path: "world"}];
array2 = [{path: "hello"}, {path: "hahah", text: "dsdsds"}];
//comparing array1 and array2 and returning unmatced from array1
Object.keys(array1)
.filter((val, index) => array1[index].path !== array2[index].path)
.map((val, index) => array1[index]);
// output
//[{"path": "world"}]Copyright © 2021 Codeinu
