Debugging React: From Taking a Deep Breath to Finding the Root Cause

Debugging React: From Taking a Deep Breath to Finding the Root Cause We've all been there. You've just pushed what you thought was a brilliant new feature, you refresh the page, and... nothing. Or worse, something completely unexpected. That sinking feeling in your stomach, the sudden urge to just console.log everything. Debugging, especially in a dynamic framework like React, can feel like trying to find a needle in a haystac k while blindfolded. But here's the thing: debugging isn't a dark art

How does VuReact compile Vue 3's withDefaults to React?

VuReact is a compiler toolchain for migrating from Vue to React — and for writing React with Vue 3 syntax. In this article, we will look at how Vue 3's withDefaults macro is compiled into React. To keep the examples easy to read, this article follows a few simple conventions: All Vue and React snippets focus on core logic only, with full component wrappers and unrelated configuration omitted. The discussion assumes you are already familiar with the API shape and core behavior of Vue 3's withDefa

I Built a Zero-Dependency React Rich Text Editor — Here's How to Use It

Build a Lightweight Rich Text Editor for React (Zero-Dependency Core) Every React application eventually needs a rich text editor. Whether you're building a blog platform, CMS, admin dashboard, knowledge base, or comment system, there comes a point where a simple isn't enough—but a full document editor is overkill. Popular libraries like Draft.js, Quill, Slate, and TipTap are excellent, but they often come with trade-offs: 📦 Larger bundle sizes 🔌 Multiple dependencies ⚙️ More setup than a simp

Backpropagation Is Just Dynamic Programming (I Animated It to Prove It)

Everyone learns backpropagation as "apply the chain rule." Almost nobody explains why it's fast — and that "why" is the whole reason deep learning is computationally possible at all. So I animated one full training step to show the part most explanations skip. What you're actually seeing Forward pass: a single signal travels through 3 weights → a prediction → compared to the target = the loss. Backward pass: the error (δ) flows back through the network. δ₃ is computed at the output, then reused
