pipe js file to eval?

That error was due to me not incorporating the core.js file. So I did:

eval(require('fs').readFile("core-min.js"));
  eval(require('fs').readFile("aes-min.js"));

I am now getting the out of memory error. For a test I commented out the aes file and just loaded the core-min.js. I didn't get the out of memory error when just loading the core-min.js file.
