This blog post discusses the top challenges faced by web developers in 2021 based on a quarterly survey. The findings reveal that the top pain points remain consistent with previous years, including browser compatibility, testing, documentation, debugging, framework usage, and security/privacy concerns. The survey data highlights the difficulties developers face in keeping up with evolving web standards and the ever-expanding ecosystem of tools and frameworks. Cross-browser compatibility and testing remain significant hurdles. While initiatives like Compat 2021 aim to address these challenges, their impact is yet to be fully realized. The data consistently shows the need for improved developer tooling and a more streamlined web development experience.
This post explores the concept of "reverse polyfilling" – creating polyfills for features removed from web browsers. I argue that as the web platform matures, pruning less-used features is necessary for performance and maintainability. While this might seem disruptive to developers, reverse polyfills, combined with the principles of the Extensible Web, offer a solution. By focusing on core primitives and building higher-level features with JavaScript (potentially leveraging technologies like WebAssembly), we can create a more adaptable and efficient web platform. Reverse polyfills will become essential for both removing legacy features and implementing new ones, contributing to a progressively enhanced web experience.
The IE team has announced that some CSS hacks used to fix issues in IE5 and IE6 won't work in IE7. This means web developers targeting IE7 will need to update their sites to address these breaking changes. The IE team encourages developers to check for common CSS hacks and replace them with standards-compliant code or conditional comments. While a CSS-based solution would be ideal, there currently isn't a standard for this issue, prompting a call to action for developers to update their code and support the move towards better standards compliance.
I just read on the IE Team's Blog that Internet Explorer 7 will have native support for XMLHttpRequest and a rebuilt, windowless select element. This is huge! Native XMLHttpRequest means no more ActiveX security issues. And a windowless select element? Finally, we might have proper layering and styling. Fingers crossed these features make it into Beta 2!
