How to get the difference of two string arrays?

Question

I want to get the exact difference between two string arrays.

const array1 = [\'T\',\'E\',\'A\',\'P\',\'A\',\'P\',\'E\',\'R\'];
const array2 = [\'T\',\'A\',\         


        

Answer 1

I think filter is not correct apparoch here. Because there are some elements repeadted. Use a simple for-loop. And remove the elements when you add it to result.

const array1 = ['T','E','A','P','A','P','E','R'];
const array2 = ['T','A','P'];
const copy = [...array2];

let res = [];
for(let i = 0;i
