- Develop the JS code
- Create bug
- Include calls to the alert() method to troubleshoot
alert() is bad for debugging
I’m sure this process sounds familiar to many of you, but do you know what, the alert() method is a very weak way of troubleshooting. I abandoned it years back because of poor features such as outputting object representations as ‘[object]‘ or ‘[undefined]‘ – which doesn’t give you a lot to go on.
So where does it output to? On the console tab of course. I almost always use Chrome these days and you’ll find the console tab if you open Chrome’s Developer Tools. It’s similarly placed within Firebug for Firefox.
For those who’d like to learn more about the console library here’s an excellent article. There you’ll see that the library has far more to offer than just the log() method.
