I would like to calculate distance from origin for some points. I don't know how to do that in Javascript.

If `x` and `y` are the co-ordinates of a point `distanceFromOrigin=sqrt(x^2 + y^2)`.

So far, below is the code I could get running in HTML:

```
<html>
<head>
<script id="vertices">
float distanceFromOrigin;

void
main()
{
distanceFromOrigin=(x * x) +(y * y);

}
</script>
</head>
</html>

```

How to add a square root to the above variable distanceFromOrigin. And also is there a power function instead of doing `x*x`?
