Freelancer provides both minified and unminified script files, with the minified versions being the ones used by default for greatest efficiency. But if you need to do some debugging for a script related issue you can defined the following constant in your Child Theme’s functions.php file to force Freelancer to use the unminified versions of the scripts for greater readability of those js files.
define( 'FREELANCER_SCRIPT_DEBUG' , true );
