return unique elements comparing arrays javascript code example
Example 1: find unique values between multiple array
var array3 = array1.filter(function(obj) { return array2.indexOf(obj) == -1; });
Example 2: return uncommon from two arrays js
let array = [1,2,3,4,5,6,78,9];
function except(array,excluded){
let newArr,temp,temp1;
check1=array.filter(function(value)
{
return excluded.indexOf(value) == -1;
});
check2=excluded.filter(function(value)
{
return array.indexOf(value) == -1;
});
output=check1.concat(check2);
return output;
}
except(array,[1,2])
//so the output would be => [ 3, 4, 5, 6, 78, 9 ]
