Hi,

My solution for merging two sorted arrays is as below.

function mergeArrays(arr1, arr2) {

var newArray= [];

for(let i of arr1){

newArray.push(i)

}

for(let i of arr2){

newArray.push(i)

}

newArray.sort();

return newArray;

}

console.log(mergeArrays([1,3,4,5],[-2,2,6,7,8]))

this algorithm gives me the desired output:

```
[-2,1,2,3,4,5,6,7,8]
```

But then why this algorithm fails one test case?

Also, please tell me what would be the run time of this algorithm.

Thanks.
