Performance clearly matters to users. For example, the most common software update on the AppStore is "Bug fixes and performance enhancements." Now that Moore's Law has ended, programmers have to work hard to get high performance for their applications. But why is performance hard to deliver? I will first explain why current approaches to evaluating and optimizing performance don't work, especially on modern hardware and for modern applications. I then present two systems that address these challenges. Stabilizer is a tool that enables statistically sound performance evaluation, making it p...

Blog post: https://mathiasbynens.be/notes/shapes-ics JavaScript has definitely been among the most influential technologies for almost a decade now. A lot of this is due to the sophisticated JavaScript VMs in modern browsers, Node.js and Electron. In this talk we’re going to explore important ingredients of these modern JavaScript VMs, specifically how ChakraCore, the engine that powers Microsoft Edge, and V8, the engine that powers Google Chrome, compare to each other for certain key features.

INTO THE WEEDS OF CSS LAYOUT There are lots of reasons to get excited about new layout methods in CSS, but what impact does moving to Flexbox and Grid have on performance? And once you have decided to adopt new layout methods, are some techniques more performant than others? In this talk we’ll take a serious look at the algorithms your browser is using in order to lay things out using Flexbox and Grid. By understanding how these algorithms work, you’ll be in a better position to make good decisions around layout, and fully take advantage of the possible performance gains of new CSS layout.

React’s unique strength is bringing to JavaScript development some of the benefits previously exclusive to more radically functional languages such as Elm an...
