Here is my problem statement.
I have two arrays
assignedArr = [{ id: 'abc1' }, { id: 'abc2' }, { id: 'abc3' }];
unAssignedArr = [{ id: 'abc1' }, { id: 'abc2' }, { id: 'abc3'}, { id: 'abc4' }];
I have to compare assingedArr with unAssignedArr, and return the unmatched array item.
For example, In the above example,
the result should be
newArr = [{ id: 'abc4' }];
Like soo...
Any suggestions would greatly appriaciated
You could use array Array.prototype.filter with Array.prototype.some method to get your result.
const assignedArr = [{ id: 'abc1' }, { id: 'abc2' }, { id: 'abc3' }];
const unAssignedArr = [
{ id: 'abc1' },
{ id: 'abc2' },
{ id: 'abc3' },
{ id: 'abc4' },
];
const ret = [
...unAssignedArr.filter((x) => !assignedArr.some((y) => x.id === y.id)),
...assignedArr.filter((x) => !unAssignedArr.some((y) => x.id === y.id)),
];
console.log(ret);
