How to get the difference between two arrays of objects in JavaScript

Question

I have two result sets like this:

// Result 1
[
    { value: \"0\", display: \"Jamsheer\" },
    { value: \"1\", display: \"Muhammed\" },
    { value: \"2\",         


        

Answer 1

I found this solution using filter and some.

resultFilter = (firstArray, secondArray) => {
  return firstArray.filter(firstArrayItem =>
    !secondArray.some(
      secondArrayItem => firstArrayItem._user === secondArrayItem._user
    )
  );
};
