I'm trying to convert a function from Javascript to CoffeeScript. This is the code:

function convert(num1, num2, num3) {

    return num1 + num2 * num3;

}

But how I can do that in CoffeeScript?

I'm trying to run the function from an HTML source like this:

<script type=text/javascript src=../coffee/convert.js></script>



<script type=text/javascript>

    convert(6, 3, 10);

</script>

But it won't work and I get an error saying: ReferenceError: Can't find variable: convert

How to correct this?
