I don't get it. Is console.log a really annoying artefact that node.js creates or something?

  console.log is a debug statement used in Javascript code. However is not supported in older browsers like IE8... If you forget to remove then, IE8 will crash and burn... It may also affect performance, although that is usually negligible...

    Stripping out console.log as part of a build process tends to be the ideal solution, but on smaller projects it's nice to leave them intact so the below is my preferred method: if (typeof console == "undefined") { console = { log: function() {} }; };

    > console.log is a debug statement used in Javascript code. However is not supported in older browsers like IE8... That is not quite correct. IE8 (and IE9 I believe) support `console.log`, but only when the developer tools are open. Needless to say, it is rather frustrating.

      isn't that also true of the other browsers?

        No.

        It is true for Firefox 4 and older.

        Not that I know of. It was probably an issue in Firefox if Firebug wasn't installed before it got built-in devtools.

  That was silly of me. I've used console.log countless times before. I just never thought of it as a thing that could be 'burned'.
