Recommended way to include a JavaScript file

Hi All,

Can anyone tell me the recommended method to include a new JavaScript file with the Responsive Child Theme?

I have done a Google and found about 9 different ways so I thought I would come straight to the horses mount and ask here.

The method I like the most is to add a functions.php to the child theme and put;-

<?php

function myJS_link() {
echo ‘<script language=”javascript” src=”JavaScriptFileName.js”>
</script>’ . “\n”;
}
add_action( ‘wp_head’, ‘myJS_link’ );

Is that a good way of doing it?

Thanks heaps

Neil
