Nub is a comprehensive JavaScript/TypeScript toolkit that brings Node.js developer experience closer to Deno or Bun. This post is an overview of Nub and the various ways you can use it. I still have a few projects that use Bun, and I’ve written about using Bun as a runtime or tool. For a demo, a small internal tool or a one-off script, Bun let me write TypeScript and run it immediately. I did not need to choose between ts-node and tsx, set up TypeScript tooling or make a custom loader.

In the previous chapter, I said that Odin lets you write useful data-oriented APIs without reaching for Class-based inheritance and polymorphism. Let’s explore what that means in this chapter. If you come from a language like Java or C#, your instinct for “many types, one operation” is to define an interface or abstract class. You’d be disappointed to learn that Odin does not have interfaces. It has no methods, no classes, and no inheritance either.

The useful part of the ECMAScript 2026 standard for JavaScript developers is not a dramatic change to the language. It is that several common use cases now have direct names. JavaScript gets a new language standard every year. Some editions introduce syntax that changes how programs are written or how they perform. The ECMAScript 2026 (ES17) version brings a handful of useful features which we will look at.
