No language is immortal—Node.js isn’t either—but thoughtful reflection is priceless. This underground community for Node.js enthusiasts was started by Taobao’s Front‑End Team (FED) to share our original insights and viewpoints from working with Node.js. Follow us. BTW, we’re hiring.
This article explains the rarely understood ES6 features WeakMap and WeakSet, compares them to Java’s weak references, and demonstrates practical Node.js and front‑end use cases such as memory‑safe context storage, result caching, and tracking unhandled promise rejections.
Node.js 13.2.0 removes the experimental flag, making ES module support stable and defining clear rules—file extensions, package.json type fields, and runtime flags—to decide whether a file is loaded as an ES module or a CommonJS module.
This article explains how V8 reduces the number of microtasks created by async/await by eliminating redundant Promise wrappers and streamlining then‑handlers, showing the original transformation code, the optimizations applied, and the resulting execution order in both browsers and Node.js.
This article explains how V8’s compiler, garbage collector, and a bug‑inspired optimization improve async/await performance across Node.js versions, detailing benchmark results, code behavior differences, and the engine’s internal steps for handling await.
The OpenJS Foundation launched two professional Node.js certifications—JSNAD for application development and JSNSD for service development—detailing eligibility, domain competencies, exam format, costs, and the foundation's role in supporting the JavaScript ecosystem.
