This article is about implementing rate limiting in a Node.js API. Learn the why and how, compare algorithms (fixed window, sliding window, token bucket, leaky bucket), and see working Express middleware examples (in-memory and Redis-backed) with best practices for headers, testing, and production hardening.

In JavaScript, the for..of loop works perfectly with arrays, strings, and other iterable objects, but it does not work with plain objects. This article explains why for...of cannot be used directly on objects, how iteration works in JavaScript, and different ways to fix or work around the issue with practical examples.

Closures are one of the most powerful features in JavaScript. They allow functions to remember variables from their outer scope, even after that scope has finished executing. This article explains closures in simple words, why they are important, and how they are applied in real-world programming.

Migrating a React project to Next.js with the new App Router architecture can bring performance improvements, server-side rendering, and simplified routing. This guide explains step by step how to move from a traditional React project to Next.js App Router.

Promises and async/await are two important tools in JavaScript for handling asynchronous operations. This article explains what promises are, how they work, how async/await improves readability, and when to use each.

Debouncing and throttling are two important techniques in JavaScript that improve performance by controlling how often functions run in response to events. This article explains what they are, how to implement them, and when to use each.
