# Diff in Two Arrays

Tell us what’s happening:
Can I solve the problem through this solution? If I can then what changes should I made.

``````function diffArray(arr1, arr2) {
var newArr = [];
// Same, same; but different.
var result;
var result1;
for(var i=0;i<arr1.length;i++)
{

for(var j=0;j<arr2.length;j++)
{

if(arr1[i]!==arr2[j])
{
//         var value=arr1[i];
//         console.log(value);
result = arr1[i];
newArr.push(result);

}

else if(arr2[j]!==arr1[i])
{
result1 = arr2[j];
newArr.push(result1);
}

else
{
console.log("Both are equal");
}

}

}

return newArr;

}

diffArray([1, 2, 3, 4, 5],[1, 2, 3, 5]);

Your logic is way off. See below where I added 3 console.log statements, so you can see what the values are for the comparisons and what is getting pushed. Use your browser’s console (Ctrl+Shft+J in Chrome) to see the results.

``````function diffArray(arr1, arr2) {
var newArr = [];
// Same, same; but different.
var result;
var result1;
for (var i = 0; i < arr1.length; i++) {
for (var j = 0; j < arr2.length; j++) {
console.log('arr['+i+'] = ' + arr1[i] + ', arr['+j+'] = ' + arr2[j]);
if (arr1[i] !== arr2[j]) {
result = arr1[i];
newArr.push(result);
console.log(arr1[i] + ' was not equal to ' +  arr2[j] + ', so pushed ' + result);
}
else if (arr2[j] !== arr1[i]) {
result1 = arr2[j];
newArr.push(result1);
console.log(arr2[j] + ' was not equal to ' +  arr[i] + ', so pushed ' + result1);
}
else {
console.log("Both are equal");
}
console.log()
}
}

return newArr;
}
