- How to Optimize CSS and JS for Faster Sites
- Website loading speed is crucial to the user experience, which is often overlooked by website owners. Raising website loading speed from 8 seconds to 2 seconds can increase conversion rate by 74%, meaning slow websites may lose nearly half of their potential customers. Code compression, i.e. removing characters that are only used to improve readability, can reduce bandwidth usage and increase page loading speed. Tools like CSS Miniifier and JSCompress can help you through this process. Furthermore, it is also worthwhile to consider implementing asynchronous code loading to further optimize performance before compressing JavaScript. Redundant or duplicate code can also slow down the website. Using Google Chrome's built-in developer tools can help identify and delete these without necessity

- Capture and Report JavaScript Errors with window.onerror
- Core points window.onerror is a browser event that is triggered when an uncaught JavaScript error is thrown, providing a simple way to log client errors and report them to the server. All modern browsers support this event, but implementation details vary. The Error object passed to window.onerror is very valuable for debugging because it contains an error stack trace that provides the source location for each frame when a program errors. However, the stack attribute is non-standard and its implementation is different in different browsers. Although window.onerror is widely supported, not all browsers pass Er
