Finding first alphabetical letter in a string - Javascript

Question

I've done some research and can't seem to find a way to do this. I even tried using a for loop to loop through the string and tried using the functions `isLetter()` and `charAt(`). I have a string which is a street address for example: ``` var streetAddr = "45 Church St"; ``` I need a way to loop through the string and find the first alphabetical letter in that string. I need to use that character somewhere else after this. For the above example I would need the function to return a value of C. What would be a nice way to do this?

Accepted Answer

Maybe one of the shortest solutions:

```
'45 Church St'.match(/[a-zA-Z]/).pop();
```

Since `match` will return `null` if there are no alphanumerical characters in a string, you may transform it to the following fool proof solution:

```
('45 Church St'.match(/[a-zA-Z]/) || []).pop();
```
