No problem thank you for the questions!
I've been using DevTools for a while now, but I still use console.log's often. The challenge is, using DevTools, while great, is in itself more cognitive overhead, and depending on how involved the thing is, sometimes a console.log is enough.
That being said, when doing serious performance debugging, or profiling, or I know I'll be tweaking the design of a site for sometime, then for sure I'll open up DevTools and make sure the layout works well/the panels/panes are resized appropriately. Anyway if you want to learn more, I've got a few performance debugging videos on DevTools.
Those videos hopefully answer question 1!
For question two, it was such a fun job because we got to do so much! I worked on pretty much every Shazam page on shazam.com, webviews that appear within the native mobile app, mobile-web communication techniques so web could talk to native, all sorts of hackday projects like visualising 1 Billion Shazam Music Recognitions, end-to-end testing with Selenium WebDriver, and at some point during a hackday I even got to tinker with the recognition algorithm 🤯️
But generally speaking, it was the main shazam.com website I was working on.
Fav programming language would have to be JavaScript! But then again, while at University I did my final project in Ruby/Ruby on Rails and it was extremely nice, elegant, easy to use, quick to get started, the list just goes on. Syntactically speaking, there's parts of Ruby I think are much better than JS, but having a fav language is more than just the syntax, it's the whole ecosystem.
For the important horse duck question, is there some wiggle room here? Because I would like to say 1 horse size duck, but then we have a one-on-one discussion about how violence is not the answer, and possibly become friends? I don't think I can convince the 100 tiny horses to be my friend and to be honest think they would trample all over me or at least bite me a lot, but am confident about the symbiotic relationship me and the massive duck could have. For example I could get them groceries and they could agree not to fight me.
