Node.js Wayfinder

Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine. Although, it is not exclusively limited to the V8 engine, there are several additional engines in the JavaScript runtime space. The vast majority of applications utilize the V8 engine for their runtime, so the current posts contain information for V8 exclusively. This may be expanded in the future to include runtimes like ChakraCore 2 and SpiderNode 3. In addition, the following posts focus exclusively on Linux and related systems. There are some correlations that can be drawn to other types of *nix systems. Furthermore, some articles will explore BSD alternatives and will discuss some of the benefits and drawbacks that exist on those systems. That withstanding, the primary focus will be on Linux systems.

The information contained in this posts are not intended for developers who are new to the field or as an introduction to server side javascript programming. These posts dive very deep on Node.js and the V8 runtime, exploring topics like the following:

  • Compiler Optimizations
  • Monomorphism, Polymorphism and Megamorphism
  • Garbage Collection and Memory Management
  • Assembly (x86)
  • Bytecode (V8)
  • Signal Handling
  • Parsers and Tokenization
  • Control Flow Graphs
  • etc.

These posts are intended for the seasoned developer who wishes to dive deeper into something they already understand. Below is a list of posts associated with the topics above it will be beneficial to approach them in order, happy wayfinding!
