You’re a hotshot JavaScript developer. When people have JavaScript questions, they come to you to find answers. Your knowledge of prototypal inheritance is second-to-none. But, do you know what actually happens when your code hits the JavaScript runtime? How does the runtime store your arrays and objects in memory? You’ve heard about the JavaScript engine wars, but what are the battles being fought over?

This talk will be all about how computers execute JavaScript. Along the way, you may learn some tips and tricks that can help improve the performance of your code. Perhaps it will increase your confidence in running JavaScript on the backend. No matter what, attendees will learn a dozen new things they didn’t already know about JavaScript execution, and will leave with a dozen new questions about the language of the web!
