Question

I just had a var I believed to be equal to "" or undefined. It turned out it was equal to \r. I couldn’t see this until I wrapped the var in quotes and outputted it to the console and I saw the line break. Is their any way I could have saw \r rather than nothing? Perhaps wrapping it in some function which will output \r or \n etc.

For general you could use something like JSON:

var str = "\r";
alert( JSON.stringify(str) );
// will alert "\u000d" instead of 'nothing'
