Speed, Speed, Speed: JavaScript vs C++ vs WebAssembly

Slides from NodeConf Argentina 2018.

What's New in Node.js Core?

Slides from Node+JS Interactive 2018.

Node.js 10 just entered Long Term Support (LTS). Let’s look at some exciting new features and what the future holds for Node.js Core.

Speed, Speed, Speed: JavaScript vs C++ vs WebAssembly

Slides from RevolutionConf 2018.

In Node.js, we can use WebAssembly modules and native C++ addons. If your app has performance critical parts, should you stay in JavaScript? Or write a native C++ addon? Or use WebAssembly? We’ll look at how these options compare performance wise and which one is best for different workloads. So the next time you need to optimize for speed, you know your options.

The JavaScript Engine in Node.js: TurboFan and Ignition

Slides from NodeFest 2017. YouTube

V8 is the JavaScript engine in Node.js. Since Node 8.3, we use V8’s new compiler pipeline with TurboFan and Ignition. How can V8 be so fast and how does a Just-in-time compiler work? We’ll look at basic and not-so-basic concepts of V8 and discuss what TurboFan, the optimizing compiler, means for Node.js performance. You’ll learn how to write code that’s fast with the new compiler pipeline.
