Solution
let haStr = "Hazzzzah";
let haRegex = /Haz{4,30}ah/; // Change this line
let result = haRegex.test(haStr);

### Solution:
```js
let haStr = "Hazzzzah";
let haRegex = /Haz{4,}ah/; // Change this line
let result = haRegex.test(haStr);
```
### Explanation:
We specify the lower and upper number of patterns with ```quantity specifiers``` using curly brackets - lower is ```4``` and unlimited upper number.
