I'm mainly a backend developer working in the .NET ecosystem, but I've recently started writing much more JavaScript. I'm looking for a book or reference comparable to the classic Gang of Four design patterns book, preferably with examples that reflect modern JavaScript idioms.
I'm specifically interested in vanilla JavaScript rather than TypeScript or a framework. My goal is to build a stronger foundation in the language itself, learn how experienced developers structure reusable modules, and study well-written examples that I can apply to front-end code. Any recommended books, guides, or reference material would be appreciated.

The classic design patterns are mostly language-independent, so the Gang of Four book is still useful. The key is learning the underlying problems and tradeoffs, then translating those ideas into JavaScript rather than looking for a separate JavaScript version of every pattern.
Patterns can be implemented in JavaScript, but they often look different because the language has first-class functions, closures, prototypes, modules, and concise object composition. Avoid forcing heavyweight class hierarchies or enterprise-style abstractions onto small pieces of front-end code. Focus on simple modules, clear interfaces, reuse, and keeping the amount of shipped code reasonable.
For a growing collection of helpers, native ES modules are generally a better direction than large IIFEs. Split functionality by responsibility, export only the public functions, remove duplicated utilities, and let your build process eliminate unused code where possible.
That’s close to what I’m trying to do. I want to organize my JavaScript helpers into reusable modules, reduce duplication, avoid shipping unnecessary code, and modernize a front end that currently uses mostly Razor views with IIFE-based custom libraries.
JavaScript: The Good Parts is a classic starting point for understanding the language’s strengths, quirks, and functional features. It’s older, so it won’t cover every modern feature, but it can help build a solid foundation before diving into newer material.
That makes sense. I’m also hoping to find examples of well-implemented JavaScript that I can study, since I have a working knowledge of the language but want to improve how I structure and organize it.
