Question: In our rails rfq.js.coffee, we only have a simple js code:

```
$(function() {
  $('#need_report').change(function(){
    if ($(this).val() == true) {
      $('#report_language').hide();
    }  // end if
  });  // end change()
});  // end ready(function)

```

However this code causes an error saying that function() in first line is a reserved word. Since the first line is basically a jquery `$(document).ready(function () {})`, we have no clue why this error shows up. Any thoughts about it? Thanks so much.

Answer: 
You can't use standard JS like that in a Coffeescript file. Either rename the file to `rfq.js`, or convert it to coffeescript:

```
$ ->
  $('#need_report').change ->
    if $(this).val()
      $('#report_language').hide()

```
You can embed regular javascript by surrounding the code with back-ticks "`". I wish it worked like the other parsing languages as well...it took me lot's of unnecessary debugging and searching to figure that out. <http://coffeescript.org/#embedded>
