Event delegation is a pattern that allows you to handle events more efficiently by leveraging event bubbling. Instead of attaching an event listener to each element, you can add a single listener to a parent element, which will handle events for its child elements. In this guide, we’ll explore how event delegation works, its benefits, and practical examples of using it in your projects.Fri, 15 Mar 2024 00:00:00 GMTPerformanceFenil Sonanihttps://fenilsonani.com/articles/javascript/javascript-event-loop/https://fenilsonani.com/articles/javascript/javascript-event-loop/JavaScript’s event loop is the engine behind its asynchronous behavior, allowing it to handle multiple tasks without blocking the main thread. While JavaScript is single-threaded, the event loop enables it to manage asynchronous operations like API calls, timers, and UI events smoothly. In this guide, we’ll break down the event loop, explaining key concepts like the call stack, task queue, microtask queue, and how they interact to keep JavaScript responsive.Fri, 15 Mar 2024 00:00:00 GMTAPI DevelopmentFenil Sonanihttps://fenilsonani.com/articles/javascript/javascript-generators/https://fenilsonani.com/articles/javascript/javascript-generators/JavaScript generators provide a powerful way to handle iterative tasks, enabling you to manage complex loops, produce values on demand (lazy evaluation), and control asynchronous flows.

Each approach has unique strengths, making it suitable for different use cases.Fri, 15 Mar 2024 00:00:00 GMTNode.jsJavaScriptBackendRedisCacheIn-Memory DatabaseFenil Sonanihttps://fenilsonani.com/articles/nodejs/optimizing-performance-in-node-js-with-caching/https://fenilsonani.com/articles/nodejs/optimizing-performance-in-node-js-with-caching/Caching is a powerful technique to improve the performance of Node.js applications by reducing load on the server and speeding up response times. By storing frequently accessed data temporarily, caching helps avoid redundant calculations, database queries, and network requests. This guide covers various caching strategies for Node.js, including in-memory caching, Redis, HTTP caching, and best practices to make the most of caching.Fri, 15 Mar 2024 00:00:00 GMTNode.jsJavaScriptBackendRedisCacheIn-Memory DatabaseFenil Sonanihttps://fenilsonani.com/articles/nodejs/request-throttling-in-node-js-with-node-cache/https://fenilsonani.com/articles/nodejs/request-throttling-in-node-js-with-node-cache/Request throttling is essential for controlling the rate of incoming requests, especially in high-traffic applications where excessive requests can strain servers, increase costs, and negatively impact user experience. By using node-cache, we can create a simple, in-memory solution for throttling in Node.js. node-cache allows us to set request limits, track request counts, and enforce time-based restrictions without the need for a distributed caching system.Fri, 15 Mar 2024 00:00:00 GMTNode.jsJavaScriptBackendFenil Sonanihttps://fenilsonani.com/articles/nodejs/scaling-node-js-applications-in-production/https://fenilsonani.com/articles/nodejs/scaling-node-js-applications-in-production/As your Node.js application gains users and experiences increased traffic, scaling becomes crucial for maintaining performance and reliability.
