Abstract
JavaScript is cool (don't @ me), but how can a machine actually understand the code you've written? As JavaScript devs, we usually don't have to deal with compilers ourselves. In this talk, I’ll use visualizations to show you how the JavaScript engine handles our human-friendly code, and compiles it to code that machines understand.

2:03 Engine's work doesn't start with the interpreter, it's already started by that point - parser is a part of the V8 engine, too. Nitpicking, but might save you from developing wrong mental models.

Hello World ! I am little new to JS/Ecmascript works. In the talk Lydia Hallie mentioned some great resources to look out for better understand the inner workings of js and ecosystem inside browser. Kindly please share links to your favourites resources for me as for me its still little difficult to narrow it down to good resources. All I get in my search results are stackoverflow and medium posts XD Some Personal Blogs would be nice as SEO underestimates them
