Parag Zaveri wrote about the transition and it has clearly resonated with lots of folks! (7.5k claps on Medium as I write).
I know I have hangups about it...
We've been able to do this for years, largely for free (ignoring the costs of the computer and devices), but I'm not sure as many people know about it as they should.
TL;DR: XCode comes with a "Simulator" program you can pop open to test in virtual iOS devices. If you then open Safari's Develop/Debug menu, you can use its DevTools to inspect right there — also true if you plug in your real iOS device.… Read article
Writing code is only one small piece of being a developer. In order to be efficient and capable at our jobs, we must also excel at debugging. When I dedicate some time to learning new debugging skills, I often find I can move much quicker, and add more value to the teams I work on. I have a few tips and tricks I rely on pretty heavily and found that I give the same advice again and again during workshops, … Read article
Kayce Basques wrote an excellent interactive tutorial that explores how to debug JavaScript with DevTools. Kayce looks into a number of techniques and options that I was completely unaware of and, as he notes in the beginning of the tutorial, if you’re still using console.log to find bugs in your code (like me) then this article is written just for you (also me).… Read article

Looks like the end of an over 2 year process.
Firebug was probably the single most important tooling advancement in front-end developments short life. A glimpse of the future, indeed.… Read article
