regex giving console output in chrome console and JSBin

Interesting little pickle:

I was using JSbin to practice converting single quotes to double quotes. The readout in the JSbin console kept inexplicably giving me "\". Then when I tried running the same code in the chrome console, the switch worked fine. (Yes, I am aware that it converted the ' in "I'm"--that is not the question at hand though.)

Any idea why jsbin might have given me those backslashes in the console output?

Solution

  • Since my comment didn't satisfy you, let's look at the sources.

    Chrome dev tools, ConsoleViewMessage.js:

    elem.createTextChild("\"");
elem.appendChild(elementWhichHoldsOurString);
elem.createTextChild("\"");

    As you can see, the dev tools writes an a double quote, followed by our string, followed by another double quote.

    jsbin, proxy-console.js is what handles your console.log arguments. As you can see, it calls stringify, which explicitly escapes double quotes in strings.
