In previous articles, I talked about NodeJS internals, why NodeJS is so fast, V8 internals and its optimization tricks. That’s cool, but… Understanding these things is not enough to write high-performance NodeJS applications. You still need to know, how to profile your NodeJS…

In my previous article, I was talking about NodeJS and why it’s fast. Today, I want to talk about V8.

Last time, I talked about V8 and how it optimizes your JavaScript code. However, I didn’t talk about optimizations tricks that are applied during compilation.

Last time, I showed you how to profile your application and find the place which slows it down — bottleneck. It helps a lot with finding the place in the code that executes slow, so you can fix that.

Today, I want to tell you about one interesting project, called Kittik. The main idea behind this project is to create and show presentations which support shapes, animations, embedding code, etc… right in your terminal. Can you believe this? Ok, let’s start…
