#javascript: console lesser known features.
We’ve all used the console tools for age (Thank you Firebug) ; but most of us use only use the basic features like console.log() or console.error(). However, the console API is really powerful and offers a lot of very interesting features. Always keep in mind that the console API is not standard and is not going to be standardized. There is absolutely no guarantee that these features will be avail

Strange JavaScript Errors and How to Fix Them
JavaScript can be a nightmare to debug: Some errors it gives can be very difficult to understand at first, and the line numbers given aren’t always helpful either. Wouldn’t it be useful to have a list where you could look to find out what they mean and how to fix them? Here you go! Below is a list of the strange errors in JavaScript. Different browsers can give you different messages for the same

Debugging JavaScript Using the DevTools Debugger Keyword You can use the debugger keyword directly in your code to invoke the debugging capabilities (if any) of the JavaScr
The Fine Art of JavaScript Error Tracking
A couple of months ago, I had some downtime at work, so I tasked myself with one of my goals for the year: implement error tracking for our JavaScript applications. It’s a bit crazy to think we weren’t monitoring our front end apps until now. Especially considering our stack is heavily comprised of a bunch of SOA-style Angular and Spine apps.
