HTML5的时机到了 (It’s Time for HTML5)

HTML5 has been gaining momentum as of late. This week it achieved Proposed Recommendation status with the W3C and also got shown some love by Apple, as it became apparent that new iOS 8 features will further its development.

到最近，HTML5一直在发展。 本周， 它在W3C中达到了“建议的推荐”状态 ，并且受到了苹果的热爱 ，因为很明显，新的iOS 8功能将进一步推动其发展。

HTML5 introduced a number of new tags which help us to write more semantic markup. Here’s a guide to using the new <time> element correctly. And why stop there? You can also use the date input to create a datepicker, something that was previously only achievable with JavaScript.

HTML5引入了许多新标签，这些标签可以帮助我们编写更多的语义标记。 这是正确使用新的<time>元素的指南。 为什么停在那里？ 您还可以使用日期输入来创建datepicker ，这是以前只能通过JavaScript实现的。

The <picture> element offers a declarative approach towards image resource loading and the <progress> element has opened a whole new avenue for providing visual feedback on long-running tasks.

<picture>元素提供了一种声明性的方法来加载图像资源 ，并且<progress>元素开辟了一条全新的途径，可为长期运行的任务提供视觉反馈 。

模式，无处不在的模式 (Patterns, Patterns Everywhere)

CodePen recently introduced an area containing curated groups of design patterns to provide you with inspiration for your next project. Sweet!

Here’s a list of hot content design patterns for mobile, as well as five patterns for mobile navigation menus.

这是针对移动设备的热门内容设计模式的列表，以及针对移动导航菜单的五种模式 。

Turning to design patterns of the programming kind, Marcello La Rocca recently took a look at emerging patterns in JavaScript event Handling and reviewed the pros and cons of the each approach. Elsewhere, Mr(?) 0a offered us an easy to understand explanation of JavaScript closure and design patterns.

关于编程类型的设计模式，Marcello La Rocca最近研究了JavaScript事件处理中的新兴模式，并回顾了每种方法的优缺点。 在其他地方，Mr(？)0a为我们提供了一个易于理解JavaScript封闭和设计模式的解释 。

Finally, here’s the factory design pattern explained by example, using PHP as the language of choice.

最后，这是用example解释的工厂设计模式 ，使用PHP作为选择的语言。

本周流行语：Web组件 (Buzzword of the Week: Web Components)

Web components are a set of specifications introduced by the W3C that allow for the creation of reusable widgets (or components) on web pages and in web applications. Although browser support is currently patchy, many developers believe web components are going to fundamentally change the way we build for the web.

Web组件是W3C引入的一组规范 ，允许在网页和Web应用程序中创建可重用的小部件(或组件)。 尽管目前对浏览器的支持很少，但许多开发人员认为Web组件将从根本上改变我们为Web构建的方式。

Keen to find out more? Good! Here’s a tutorial to get you started.

渴望了解更多？ 好！ 这是一个入门指南 。

Polymer is a set of polyfills that enables us to use web components in non-compliant browsers. Here’s a guide to web components written by one of the Polymer devs. The same guy has also released YOLOmer! – a Yeoman generator for Ploymer projects.

Polymer是一组polyfill，使我们能够在不兼容的浏览器中使用Web组件。 这是由一位Polymer开发人员编写的Web组件指南 。 同一个人还发布了YOLOmer！ –适用于Ploymer项目的约曼发电机。

Web components make Jeremy Keith both excited and nervous. Read his blog post to find out why.

Web组件使Jeremy Keith既兴奋又紧张。 阅读他的博客文章以找出原因。

TJ VanToll is another developer who has been vocal on this subject. Recently he announced that web components aren’t ready for production, then back peddled and announced that in fact they are. Both articles make interesting reading.

TJ VanToll是另一位一直在这个主题上发声的开发商。 最近他宣布Web组件尚未投入生产 ，然后兜售并宣布实际上 已经投入生产 。 这两篇文章都很有趣。

程序员专区 (Programmers’ Corner)

It’s always hard to know which technologies to keep up with and what to learn to advance your career. Well, not so according to this guy, who claims that all software engineers should learn JavaScript.

总是很难知道要掌握哪些技术以及要学习什么才能促进职业发展。 嗯，这家伙并不这么认为，他声称所有软件工程师都应该学习JavaScript 。

And while we’re on the subject of what software engineers should do, here’s what y’all should know about floating point arithmetic … What do you mean 0.1 + 0.2 is not quite equal to 0.3???

在我们讨论软件工程师应该做什么的主题时，这是大家应该了解的浮点算术 ……您是什么意思0.1 + 0.2并不等于0.3？

Recently, someone on SitePoint’s forums, someone asked “Which programming language pays better?“. Whilst the answer to that is obviously “Just learn JavaScript”, here’s an interesting list of unpopular programming languages that are still lucrative.

最近，在SitePoint的论坛上有人问“ 哪种编程语言效果更好？ ”。 答案显然是“只需学习JavaScript”，这是一个有趣的， 不受欢迎的编程语言列表，它们仍然有利可图 。

I don’t know about lucrative, but here’s what’s hot according to the Tiobe Index.

我不知道利润丰厚，但是根据Tiobe Index ，这是最热门的 。

So that’s everything for this week. Thanks for joining us.

这就是本周的一切。 感谢您加入我们。

I’ll leave you with a couple of random things I came across in the course of my travels: news that the next version of IE, code-named “Spartan,” might support extensions (Madness? THIS IS SPARTA!), an ethical trap to paralyze robots and in case you missed it fartscroll.js from the Onion (just so your page can fart as you scroll).

在旅行过程中，我将带给您一些随机的事情：有关代号为“ Spartan”的IE的下一个版本可能支持扩展 (疯了？这是SPARTA！) 的消息。陷阱使机器人瘫痪 ，以防万一您从洋葱中错过了fartscroll.js (只是为了使您的页面在滚动时可以放屁)。

So which links caught your attention? What do you think about HTML5? Are web components ready for production? Which is the most lucrative programming language to learn? We would love to hear your thoughts.

那么哪些链接引起了您的注意？ 您如何看待HTML5？ Web组件是否已准备好投入生产？ 学习哪种最赚钱的编程语言？ 我们很想听听您的想法。

Also, if you have any problems implementing anything covered here, or just want to discuss it some more, SitePoint’s forums are a great place to visit.

此外，如果您在执行此处介绍的内容时遇到任何问题，或者只是想进一步讨论， SitePoint的论坛都是一个不错的选择。
