Question

I’m trying to follow the the examples here

http://eloquentjavascript.net/chapter2.html

and

print('blah');

Keeps trying to send to a physical printer when run in a browser. I just want console output.

Answer 1

If you want something simple, the Chrome console will let you run JavaScript on the fly. To print text you can use console.log('blah'); And if you want to print multiple values, you can just list them all out as arguments (no need to concatenate) console.log("a", "b", "c", 1, 2, 3);

You can bring it up with control-shift i then select the console tab on the far right. And of course FireBug has a similar feature if you’re more of a FireFox fan.
