Microsoft Gives Devs a Glimpse of HTML5-Friendly IE9
Microsoft’s release of Internet Explorer 9 (IE9) Platform Preview marks a significant departure from the company’s historical approach to web standards and developer support. This early look offers a substantial glimpse into how IE9 aims to embrace modern web technologies, particularly HTML5, and address long-standing criticisms regarding its compatibility and performance. The platform preview, accessible to developers for download and testing, focuses on core rendering and JavaScript engine improvements, providing a clear signal that Microsoft is prioritizing a standards-compliant, faster, and more developer-friendly browsing experience. This move is not merely an incremental update; it represents a strategic pivot designed to regain developer trust and encourage the adoption of IE9 as a viable platform for building cutting-edge web applications.
A cornerstone of this shift is IE9’s dramatically improved support for HTML5. While previous versions of Internet Explorer lagged significantly behind other browsers in their adoption of evolving web standards, IE9 Platform Preview demonstrates a strong commitment to key HTML5 features. This includes robust support for the Canvas API, which allows for dynamic drawing and manipulation of graphics directly within the browser using JavaScript. Developers can now create rich, interactive visualizations, games, and complex graphical interfaces without relying on plugins like Flash. The implementation in IE9 is designed to be performant, leveraging hardware acceleration where available to ensure smooth rendering of complex canvas operations. This is a crucial step for web developers aiming to create desktop-like experiences within the browser.
Furthermore, the platform preview showcases enhanced support for new semantic HTML5 elements such as <article>, <aside>, <nav>, and <section>. These elements provide better structure and meaning to web page content, improving accessibility for screen readers and search engine crawlers. By embracing these semantic tags, Microsoft is enabling developers to build more organized, understandable, and discoverable websites. This aligns with the broader goal of HTML5 to make the web more structured and semantically rich, moving away from the often overly-div-heavy, unstructured markup that characterized earlier web development. The integration of these elements into IE9 signals Microsoft’s intention to treat the web as a platform with a well-defined architecture, rather than a loosely defined collection of pages.
The inclusion of native support for audio and video embedding via the <audio> and <video> tags is another significant advancement. Previously, embedding multimedia content in IE typically required proprietary solutions or third-party plugins, leading to fragmentation and compatibility issues. IE9 Platform Preview, however, brings native support for these elements, allowing developers to seamlessly integrate audio and video playback into their web pages. This move simplifies multimedia implementation, reduces reliance on external technologies, and contributes to a more consistent cross-browser experience for rich media content. The browser’s ability to handle these elements natively also opens up opportunities for more advanced media playback controls and integration with other web APIs.
Beyond HTML5 element support, IE9 Platform Preview demonstrates a considerable leap forward in its JavaScript engine, codenamed "Chakra." This new engine is designed for significantly faster execution of JavaScript code, a critical component for modern, dynamic web applications. Developers have long cited the performance of IE’s JavaScript engine as a major bottleneck. Chakra aims to alleviate this by employing techniques such as just-in-time (JIT) compilation and parallel execution. This focus on performance is paramount for applications that involve complex calculations, real-time data processing, or intricate animations, all of which are becoming increasingly common on the web. The speed improvements offered by Chakra are intended to bring IE9’s JavaScript performance in line with, and potentially surpass, that of its competitors.
The platform preview also highlights improvements in CSS support. IE9 is showing better adherence to CSS standards, including support for more advanced properties and selectors. This allows for more sophisticated styling and layout control, enabling designers to create visually richer and more complex web designs with less reliance on workarounds. The improved CSS compliance means that designs that look good in other modern browsers are more likely to render correctly in IE9, reducing the debugging burden for web developers. This focus on CSS standards is another facet of Microsoft’s commitment to aligning IE9 with the broader web development ecosystem.
For developers, the implications of IE9’s HTML5-friendly approach are substantial. It means they can begin to leverage these modern web technologies with greater confidence, knowing that a significant portion of the user base will have access to a browser that natively supports them. This reduces the need for polyfills, feature detection fallbacks, and complex cross-browser compatibility layers that have plagued web development for years. The ability to rely on native browser capabilities for features like Canvas, audio/video, and semantic markup simplifies the development process, lowers costs, and ultimately leads to more robust and performant web applications. The development community has been vocal about their desire for better standards support in Internet Explorer, and IE9 Platform Preview appears to be a direct response to these demands.
Security and privacy are also areas where IE9 Platform Preview is making strides, though specific details are still emerging. Microsoft has indicated a focus on enhancing these aspects of the browser, which are critical considerations for any modern web platform. Improved security features aim to protect users from malicious websites and online threats, while enhanced privacy controls empower users to manage their online footprint. For developers, a secure and privacy-conscious browser environment is essential for building trust with their users.
The performance benefits of IE9 extend beyond JavaScript execution. The browser incorporates improvements to the rendering engine, with a particular emphasis on leveraging hardware acceleration. This means that certain graphics-intensive tasks, such as rendering complex layouts, animations, and video playback, can be offloaded to the graphics processing unit (GPU). This not only leads to smoother visual experiences but also frees up the CPU for other tasks, resulting in a more responsive overall browsing experience. For web developers creating visually rich applications, this hardware acceleration can be a game-changer, enabling them to push the boundaries of what’s possible on the web.
The proactive engagement with the developer community through releases like the Platform Preview is a notable shift in Microsoft’s strategy. Historically, developers have often had to wait for full browser releases or rely on beta versions to test compatibility with newer web standards. By providing early access to IE9’s core technologies, Microsoft is empowering developers to experiment, provide feedback, and adapt their development practices well in advance of the final release. This collaborative approach is crucial for fostering adoption and ensuring a smoother transition to the new browser. The feedback loop established through these previews allows Microsoft to refine IE9 based on real-world developer needs and challenges.
The implications for search engine optimization (SEO) are also noteworthy. The enhanced semantic markup in HTML5, coupled with improvements in how IE9 parses and understands web page structure, can contribute to better search engine indexing. Search engines rely on well-structured and semantically meaningful content to rank web pages effectively. By embracing HTML5 elements and providing a more standards-compliant rendering engine, IE9 can indirectly contribute to improved SEO for websites built with these technologies.
From a business perspective, Microsoft’s investment in a more standards-compliant and developer-friendly Internet Explorer is a strategic imperative. The rise of web applications and the increasing reliance on web technologies for critical business functions have made browser compatibility and performance paramount. A lagging browser can hinder innovation and create significant friction for businesses looking to leverage the web. By signaling a strong commitment to HTML5 and performance, Microsoft aims to reclaim market share and position IE9 as a competitive platform for the future of the web. This is a crucial step in re-establishing Internet Explorer as a relevant and preferred choice for both end-users and developers.
The move towards HTML5 support in IE9 also signals a broader trend of web browsers converging on a set of core standards. As more browsers embrace HTML5, the web becomes a more unified and predictable platform. This reduces the fragmentation that has plagued web development for years and allows developers to focus on creating innovative experiences rather than wrestling with browser-specific quirks. Microsoft’s participation in this convergence is a positive development for the entire web ecosystem.
The IE9 Platform Preview is not a feature-complete browser, nor is it intended for general consumer use. Its primary audience is web developers and designers who can use it to test their existing websites and begin experimenting with new HTML5 features. The focus is on the underlying rendering engine and JavaScript capabilities, which are the foundational elements for any web browser. By making these core components available for early testing, Microsoft is facilitating a proactive approach to web development, allowing developers to anticipate and adapt to the upcoming changes in Internet Explorer.
