Monotonic Stack: Solving the 'Daily Temperatures' Problem
Solve Daily Temperatures with a monotonic stack in TypeScript, storing indices to find the next warmer day without repeated scanning and common mistakes.

Development is the broadest category in my writing, so it works as the main archive rather than a narrow subject label. It brings together implementation notes and technical decisions, with delivery lessons from across the rest of the site.

Solve Daily Temperatures with a monotonic stack in TypeScript, storing indices to find the next warmer day without repeated scanning and common mistakes.

Generate valid parentheses in TypeScript with backtracking, recursion state, pruning, edge cases, and why the approach avoids invalid strings in code.

Implement a Trie prefix tree in TypeScript with Map‑based nodes, insert, search, startsWith, shared prefixes, complexity, and alternative child storage.

How to build efficient recursive functions in JavaScript, with better base cases, less repeated work, and a clearer sense of when recursion fits naturally.

Execution context defines how JavaScript code runs, from global scope to function calls. Here, I explore how it works in browsers, React, Next.js, and Node.js.

useMemo and useCallbackOptimise React performance with useMemo and useCallback only where profiling shows expensive calculations, unstable functions, or avoidable re‑renders.

Solve Binary Tree Zigzag Level Order Traversal with breadth‑first search, level sizing, alternating output order, and TypeScript implementation details.

A version‑specific investigation into Next.js 15.5.5 Middleware not firing in Pages Router, with checks, workarounds and Next.js 16 Proxy context.

How ISR improves Next.js performance by mixing static speed with controlled freshness, and where it fits best over fully dynamic rendering for changing content.

Reversing an array in JavaScript can be done with `.reverse()`, but it mutates the original array. Here, I explore immutable methods and older techniques.

Memory leaks in React can cause sluggish performance and excessive memory usage. Here, I explore common causes, how to prevent them, and debugging techniques.

How to create custom Vue directives for DOM‑level behaviour, without reaching for them when a component, prop, or composable would do better in real interfaces.

Solve Binary Tree Level Order Traversal with breadth‑first search in TypeScript, using a queue, level sizing, edge cases, and cleaner iteration.

Solve Subarray Sum Equals K with prefix sums and a hash map in TypeScript, including negative numbers, count storage, and why sliding window fails.

CSS container queries allow elements to respond to their parent's size rather than the viewport. I explain how they work and how they improve responsive design.

Build a headless CMS‑powered Next.js site with content modelling, fetch layers, mapped front‑end data, preview support, and scalable rendering choices.

Sorting complex arrays in JavaScript requires custom comparison functions. Here, I explore techniques for sorting numbers, objects, nested properties, and more.
