My post
CSS Subgrid : The Missing Piece in Complex Layout Systems
If you’ve ever struggled to align nested components perfectly across rows and columns, you’ve hit the limits of traditional CSS Grid. CSS Subgrid fixes that. This is not a beginner feature it’s layout engineering.
JavaScript Symbols : The Hidden Layer of the Language
Most devs know Symbol() creates a unique value. Advanced devs know Symbols are how JavaScript hooks into its own internals. Symbols enable meta-programming without collisions.
Unlock Low-Level CSS Power with CSS Houdini
Most devs think CSS is fixed. CSS Houdini breaks that assumption. It lets you extend CSS itself—custom properties with logic, custom layouts, custom painting—all running directly in the browser’s rendering engine.
Debounce vs Throttle: Quick Guide
Debounce executes only after inactivity (e.g., search suggestions), while Throttle executes at regular intervals (e.g., scrolling). Master these to optimize performance.
Node.js vs Bun: 2025 Performance Comparison
Bun delivers significantly faster startup times and excels in I/O-heavy tasks, while Node.js remains the stable industry standard. Which one should you choose for your next project?
Introducing Promise.try() in ES2025
Promise.try() lets you wrap any function (sync or async) into a Promise without needing to manually write new Promise() or try/catch blocks. Clean up your async workflows.
JavaScript Proxies for Metaprogramming
Start intercepting reads, writes, and even function calls on any object. Proxies unlock the door to metaprogramming—code that manipulates behavior of other code at runtime.
React’s useTransition vs useDeferredValue
These hooks are the secret to buttery-smooth UIs. useTransition prioritizes interactions, while useDeferredValue defers expensive derived values. Learn when to use which.
WeakMap & WeakSet: Secret Weapons for Memory
For high-performance apps, memory leaks can destroy performance. WeakMap allow automatic garbage collection when no references remain. Perfect for caching and DOM metadata.
