Coffeescript compile error - coffeescript

Question

i just installed Coffeescript and tried a test compile but it always drop me errors for silly things, Coffeescript only compile correctly when only Coffeescript syntax is used?
because if yes then i understand the error.
concDev.js contents:
/*! ProjectName 2013-08-18 06:08:39 */
$(function() {
// Avoid `console` errors in browsers that lack a console.
(function() {
var method;
var noop = function () {};
var methods = [
'assert', 'clear', 'count', 'debug', 'dir', 'dirxml', 'error',
'exception', 'group', 'groupCollapsed', 'groupEnd', 'info', 'log',
'markTimeline', 'profile', 'profileEnd', 'table', 'time', 'timeEnd',
'timeStamp', 'trace', 'warn'
];
var length = methods.length;
var console = (window.console = window.console || {});
while (length--) {
method = methods[length];
// Only stub undefined methods.
if (!console[method]) {
console[method] = noop;
}
}
}());
});
// New file
$(function() {
// Handler for .ready() called.
});

You can't use C style comments in Coffeescript.
This
/*! Project Name ...*/
should be this
# Project Name ...
More generally, if you're using the Coffeescript compiler, you need valid coffeescript syntax and can't mix and match JS and coffeescript files.
Update
You're trying to pass a JS file to a coffeescript compiler. The coffee compiler accepts a coffeescript file, and compiles it to a JS file. Your file in Coffeescript would look something like this:
#! ProjectName 2013-08-18 06:08:39 */
$ ->
# Avoid `console` errors in browsers that lack a console.
do ->
noop = -> null
methods = [
'assert', 'clear', 'count', 'debug', 'dir', 'dirxml', 'error',
'exception', 'group', 'groupCollapsed', 'groupEnd', 'info', 'log',
'markTimeline', 'profile', 'profileEnd', 'table', 'time', 'timeEnd',
'timeStamp', 'trace', 'warn'
]
length = methods.length
console = window.console = window.console || {}
while length--
method = methods[length]
# Only stub undefined methods.
if !console[method]
console[method] = noop;
// New file
$ ->
#Handler for .ready() called.
If you really need to have some JS in your coffeescript file, you can embed it using backticks like this
a = `(function() x{ return 2;})()`
