Is there a better way to do square in a list rather than this?

Question

I am trying to simplify a square call. Is this the best way? ``` (1 to 10).map(x => x*x) ```

Accepted Answer

Declare this once somewhere:

```
def sqr(x: Int) = x * x
```

And use it like this afterwards:

```
(1 to 10).map(sqr)
```
