How to access logger from lang-javascript

I have just started using lang-javascript for calculating a custom score,
and want to debug the script I have written. I checked out the following
links:

https://groups.google.com/forum/#!searchin/elasticsearch/javascript$20log/elasticsearch/NwTjyJ35ZoU/ffEPiJq_K0QJ

Redirecting to Google Groups

and searched through elasticsearch documentation but am unable to figure
out how to log from within the lang-javascript script. Can anyone point to
any relevant documentation or give an example?

Thanks
