**Tell us what’s happening:**

Describe your issue in detail here.

I am unable to pass the No repeats pleasechallenge. The function that I have written to get all permutations of a given string is returning an array of permutations of a string where each item in an array is a string. For example perm(‘aabb’) returns an array of length 24. But upon filtering the array returned by function ‘perm’, I am unable to get the correct filtered array. Upon filtering perm(‘aabb’), for example, I am getting [‘baba’, ‘baba’, ‘baba’] as a result. According to the tests, it must contain 8 items. Can someone please help>

```
**Your code so far**
```

```
function permAlone(str) {
let result=perm(str)
let regex = /(.)\1+/;
const filtered = result.filter(function(string) {
return !string.match(regex);
});
console.log(filtered)
return filtered.length
}
/*This function removes the first letter of the string and find permutations of the remaining letters recursively. After finding the permuatations of remaining letters, it inserts first letter at different positions to generate all possible permutations*/
function perm(s){
if(s.length<2){
return [s]
}
let result = perm(s.slice(1))
let temp=[...result]
for (let i=0;i<result[0].length;i++){
result.push(...temp)
}
for (let i=0;i<result.length;i++){
result[i]=result[i].slice(0,i)+s[0]+result[i].slice(i)
}
return result
}
permAlone("aabb")
```
