Summary Throttling and debouncing are two techniques in JavaScript used to control how often a function is executed, especially during high-frequency events like resizing or scrolling. Properly implementing these techniques can help improve Interaction to Next Paint (INP), enhancing user experience by maintaining smoother and faster interactions. This guide provides

Summary First Input Delay (FID) is a crucial web performance metric that measures the time from when a user first interacts with a page to the time when the browser is actually able to begin processing event handlers. Effective tools for measuring FID include Lighthouse, Chrome User Experience Report (CrUX)

Summary Improving First Input Delay (FID) involves optimizing web application performance to ensure that user interactions are prioritized and processed swiftly. This comprehensive guide covers techniques like breaking up long tasks, optimizing JavaScript execution, leveraging web workers, and using modern browser APIs to enhance FID. Breaking Up Long Tasks Identify

Summary Asynchronous loading of non-critical JavaScript and CSS files can significantly improve First Input Delay (FID). By loading these assets asynchronously, the browser can prioritize rendering the main content and executing critical tasks, leading to a more responsive user experience. Here’s a deep dive into why this technique is

Summary Reducing the impact of third-party scripts on First Input Delay (FID) can be achieved by optimizing script handling, employing strategic loading techniques, and minimizing the usage of unnecessary third-party resources. This guide provides various strategies and examples to improve FID effectively. Optimize Script Handling Asynchronous and Deferred Loading One

Summary Server-side rendering (SSR) influences First Input Delay (FID) by providing a faster initial load and better interactivity, reducing the time to First Contentful Paint (FCP). However, optimizing SSR involves specific best practices such as reducing JavaScript payloads, implementing progressive hydration, and using web workers. Here’s a detailed guide

Summary Breaking up long JavaScript tasks into smaller chunks significantly enhances First Input Delay (FID) on complex web pages. This technique helps ensure that the main thread remains responsive, enabling faster user interaction. The following detailed breakdown explains how this approach works, provides specific strategies, and offers examples to improve

Summary Web fonts significantly influence First Input Delay (FID), a crucial metric for user experience on the web. Optimizing web font loading can enhance FID by reducing the time users spend waiting for the first interaction to be processed. This guide details ways to optimize web fonts effectively to minimize

Summary Reducing the impact of third-party scripts on First Input Delay (FID) is crucial for enhancing web performance and user experience. Strategies include deferring non-essential scripts, lazy loading, optimizing script execution and delivery, and limiting the number of third-party requests. Here’s a comprehensive guide to effectively mitigate the negative

Summary Effective use of a browser's cache mechanisms can significantly reduce First Input Delay (FID) for returning visitors by ensuring faster loading of critical resources. Leveraging strong caching strategies ensures that returning users experience reduced page load times and smoother interactions, as key resources do not need to
