I have a RegEx to check the finite repetition of alphabets as well as for numbers in two separate RegEx, but I am trying to combine to one RegEx but it is always returning true.

```
// Alphabetes testing:
/([a-z])\1{4,}/.test("sd0") => false
/([a-z])\1{4,}/.test("adsssssd0") => true
// Numeric testing:
/([0-9])\1{3,}/.test("sd00000ds") => true
/([0-9])\1{3,}/.test("sd00s00ds") => false
/(([a-z])\1{4,})|(([0-9])\1{3,})/.test("sd0sds0sds") => true // always true

```

Thanks.
