据国外媒体报道，上周五在澳大利亚悉尼市举行的微软Tech-Ed技术大会上，该公司高级项目经理斯科特·汉塞尔曼(Scott Hanselman)称，微软Silverlight在线视频技术最大竞争对手并不是Adobe的Flash，而是谷歌(Google)、Mozilla等公司正大力推广使用的JavaScript技术。
汉塞尔曼当天表示：“今后18个月内，谷歌和Mozilla技术开发人员将加大研发力度，从而使JavaScript运行速度比当前增长100倍甚至1000倍。此举将对微软Silverlight技术构成重大威胁。”谷歌上周二推出了其Chrome浏览器，并在全球范围内受到普通网民和业界专家的极大关注。谷歌称，Chrome采用了JavaScript技术，目的是使Chrome运行速度更快。
全球知名咨询公司凯捷(Cap Gemini)高级顾问琼那斯·弗莱索(Jonas Folleso)也认为，随着今后JavaScript运行速度加快，谷歌Chrome整体速度肯定也会大幅提高，“谷歌在Chrome中采用了JavaScript和JavaVM技术，从而使浏览器具备高速运行能力。”他认为，浏览器开发者在JavaScript整合上遇到问题时，总会有JavaScript专家出来“排忧解难”。
弗莱索说：“在应用程序开发事宜上，我们很难判断应该选择Silverlight还是JavaScript。我个人的看法是，相较于Flash，JavaScript对Silverlight的威胁程度更大。”
一名与会者现场发问：“我是否应该马上买些JavaScript书籍来看看?我原先那点JavaScript知识早忘光了。”。微软另一名项目经理哈里·佩尔森(Harry Pierson)回答道，对于绝大多数开发者而言，JavaScript是一门非常怪异的语言，业界是否有必要对其进行更高级别的开发和编译，这将是非常有意思的话题。
汉塞尔曼却认为，虽然JavaScript确实是门“非常怪异”的语言，但开发者仍可借助JavaScript开发出很有创意的程序，“与我曾在Netscape 4中使用并厌恶的JavaScript相比，如今的JavaScript已完全不同。所以我的回答是，你们确实应该买几本JavaScript书籍看看。”
弗莱索认为，虽然今后JavaScript将占据市场优势地位，但Silverlight也会得以发展壮大，尤其Silverlight将在企业Web 2.0领域具有很大增长潜力，“对于企业用户来说，如何他们想要获得普通网民的Web 2.0体验，使用HTML和JavaScript手段来实现该目的并非易事，而Silverlight就可成为更易使用的替代方案。”
“I think that the next 18 months we’re going to see a 100- to 1,000-fold speed increase in JavaScript as Google and the guys at Mozilla are going to kick us all in the arse and make our JavaScript jittered,” Microsoft senior program manager Scott Hanselman told the audience Friday, days after Google released its Chrome browser, which features faster JavaScript technology.
Jonas Follesø, senior consultant at Cap Gemini, agreed, saying that JavaScript would continue to get speedier and that Chrome will become “massively” faster than it is.
“Now Google has stepped up and released a browser with jittered JavaScript and JavaVM, making this really, really, really fast,” he said.
The consultant said that whenever he thought people had reached a limit about what could be done inside a browser using just JavaScript, some “cool JavaScript writer” came up and showed him how to do more.
“It’s going to be hard to tell if it’s going to be Silverlight or JavaScript we’re going to use for our applications,” he said. “I think in the end JavaScript is going to be a bigger competitor to Silverlight than Flash is.”
An audience member questioned the panel of experts later on whether he should “be out buying JavaScript books” now the language had been “put on steroids.”
Harry Pierson, Microsoft program manager, answered that he thought “JavaScript is a very odd language for most developers” and that it was more interesting to do higher-level development and if necessary compile it down to JavaScript.
Hanselman had a different opinion, saying that although it was a “freaky, weird language,” it was possible to do object-oriented programming. “The JavaScript I used and hated in Netscape 4 is not the same JavaScript we have today,” he said. “So yeah, I think you should get some JavaScript books.”
Follesø said that even if souped-up JavaScript became dominant, he thought Silverlight was going to be big, especially in the enterprise when “fun” Web 2.0 applications come to roost. “For the intranet, when the users expect the same kind of user experience it’s not that easy to really build that stuff in HTML and JavaScript, so Silverlight might be a lot easier alternative,” he said.
