JavaScript 開發者年度調查報告(2016-01)

JavaScript 開發者年度調查報告

There were over 5000 responses, 5350 to be exact, and I can’t wait to share the details. Before that I want to thank everyone who chipped in. This is a great time to be a part of the JavaScript community, and I’m truly excited for things to come!

截止目前有超過了 5000 人蔘與了(該次調查)，準確的說是 5350 人。我火燒眉毛的想要和你們分享一下此次調查的細節。在分享以前我想要感謝參與調查的每個人。這是 Javascript 社區一個偉大的時刻，我對將來的事情感到無比激動。

I didn’t anticipate such high interest, and next time I’ll make some improvements to the format. Namely, I’ll put the survey up on GitHub first so that the community can collaborate on the questions and options for a couple of weeks before launching the survey. That way, I’ll be able to produce more accurate results and avoid complaints like 「I am shocked you didn’t include Emacs!」.

我沒有想到你們如此積極，下一次我必定會對版式作一些改進。換句話說，就是我會先將問卷調查放到 Github 上，以便於在開始調查以前，社區有一到兩週的時間來收集改進問題和選項。這樣，我就能夠獲得更精確的結果，也能夠避免出現諸如 「我很震驚你居然沒有包含 Emacs」 這樣的抱怨。

Now, onto the survey results. I’ll remain impartial in delivering the results, so that you can come to your own unbiased conclusions.

如今，基於調查結果。我將保持中立的態度發表一下調查結果，這樣你就能夠得出本身的公正的結論。

##What type of JavaScript do you write?

你寫什麼類型的 Javascript？

A whooping 97.4% of respondents write JavaScript for a web browser, while 37% of them write mobile web applications. Over 3000 of them – with 56.6% – also write server-side JavaScript. Among those who took the poll, 5.5% use JavaScript in some sort of embedded environment, such as Tessel or a Raspberry Pi.

有高達 97.4% 的受訪者用 Javascript 寫 web 瀏覽器程序，其中有 37% 的受訪者寫移動端 web 程序。超過 3000 人(56.6%) 也寫服務端的 Javascript。在這些參與調查者的人中間，有 5.5% 的人還在一些嵌入式環境中使用 Javascript，例如 Tessel 或 a Raspberry Pi (樹莓派).

A few participants replied they use JavaScript in some other places, notably in developing CLI and desktop applications. A few also mentioned Pebble and Apple TV. These fell in the Other category, with 2.2% of the votes.

少數參與者表示他們也在其餘一些地方使用 Javascript，尤爲是在開發 CLI 和桌面應用方面。還有少數提到了 Pebble 和 Apple TV. 這些都歸類在 Other 一類中，佔總票數的 2.2%.

Where do you use JavaScript?

你在哪裏使用 Javascript？

Unsurprisingly, 94.9% of voters use JavaScript at work. However, a large portion of the tallied – with 82.3% of the votes – also use it on side projects. Other responses included for teaching and learning, for fun, and for non-profits.

不出所料地，有 94.9% 的參與者在工做中使用 Javascript，可是，統計中也有很大一部分(佔總票數的 82.3%) 參與者也在其餘項目中使用。其餘的回覆則包括了教學，好玩，和非盈利目的的使用。

How long have you been writing JavaScript?

你寫 Javascript 多長時間了？

Over 33% of the surveyed have been writing JavaScript code for over six years. Out of those who answered the poll, 5.2% started at most a year ago, 12.4% two years ago, and 15.1% three years ago. That makes it 32.7% people who started writing JavaScript in recent years, out of 5350 voters.

超過 33% 的受訪者表示他們寫 Javascript 代碼已經超過了 6 年時間。除了這些人以外，有 5.2% 的人一年前開始寫 Javascript 代碼，12.4% 的人是兩年前，還有 15.1% 的人是三年前。這說明在 5350 個投票者中，有 32.7% 的人是在近幾年纔開始寫 Javascript 的。

Which compile-to-JavaScript languages do you use, if any?

若是能夠的話，你使用哪一種 compile-to-JavaScript(編譯爲 JavaScript 的) 語言？

A whooping 85% replied that they compile ES6 into ES5. Meanwhile 15% still use CoffeeScript, 15.2% use TypeScript, and a measly 1.1% reported they use Dart.

有高達 85% 的受訪者表示他們使用 ES6 編譯成 ES5。與此同時，有 15% 的人仍然使用 CoffeeScript，15.2% 的人使用 TypeScript，只有區區 1.1% 的人使用 Dart.

This was one of the questions I wish I’d approached more collaboratively, as it got 13.8% of 「Other」 responses. The vast majority of these answers were ClojureScript, elm, Flow, and JSX.

這是我想進一步探討的問題之一，由於有 13.8% 的人選擇了 「Other」，選擇 「Other」 的絕大部分的回答是 ClojureScript, elm, Flow, 和 JSX.

彷佛大部分投票者都使用 Mocha 或是 Jasmine 來運行他們的 Javascript 測試用例。而 Tape 收到了 9.8% 的選票。

What code quality tools do you use?

你使用過哪一個代碼質量檢測工具？

It would seem like respondents are divided between ESLint and JSHint, but JSLint is surprisingly strong after all these years, at almost 30%.

How do you prefer handling client-side dependencies?

你經過哪一種方式來處理客戶端依賴關係？

npm took over as the client-side dependency management system of choice, with 60% of the votes casted their way. Bower still holds 20% of the audience, and plain old <script> downloading and insertion managed to get 13.7% votes.

npm 接管了客戶端依賴管理系統的天下，有超過 60% 的投票就是證實它的方式。Bower 仍然有 20% 的觀衆，而經過下載和插入 <script> 標籤來管理的普通舊式方法則得到了 13.7% 的選票。

What’s your preferred build script solution?

你首選的腳本構建方案是什麼？

Build tooling choices are divided, partially due to the healthy amount of different options to choose from. Gulp is the most popular, with over 40% of the votes. Using npm run is close by, at 27.8%, and Grunt got 18.5% of the audience.

構建工具的選擇很分散，部分緣由是有太多的不一樣的選項可供選擇。Gulp 最流行，有着超過 40% 的選票，緊接着的是使用 npm run，有 27.8%。Grunt 獲得了 18.5% 的支持者。

What’s your preferred JavaScript module loading tool?

你首選的 JavaScript 模塊加載工具是什麼？

At the moment, it would seem as most people are torn between Browserify and Webpack, although the latter leads by almost 7 points. 29% of users indicated they use transpile Babel modules first, before presumably using one of the two aforementioned tools to pack their modules together.

目前，看起來大部分開發者都在 Browserify 和 Webpack 之間徘徊，然後者高出了 7 個百分點。29% 的用戶表示他們在使用前面提到的這兩個工具打包他們的模塊以前會先使用 Babel 進行轉換。

What libraries do you use?

你使用過哪些庫？

In retrospect, this was one of the questions which would’ve benefitted a lot from collaborative editing. jQuery is still going strong, with over 50% of votes casted its way. Lodash and underscore are used by a significant portion of the JavaScript population that participated in the voting, while the xhr micro library only clocked in 8% of the votes.

如今回顧起來，這是一個受益於協同編輯的問題之一。jQuery 得到了超過 50% 的選票證實了它的勢頭依然很強勁。在參與投票的 JavaScript 使用者中，Lodash 與 Underscore 也被很大一部分開發者使用。 xhr 微型庫只得到了 8% 的票數。

What frameworks do you use?

你使用過哪些框架？

Unsurprisingly, React and Angular are leading the pack. Backbone is still in a healthy position, with 22.8% of the votes.

毫無心外的，React 和 Angular 遙遙領先於其餘框架，有着 22.8% 的 Backbone 仍然處在一個安全的位置。

Do you use ES6…

Responses were quite divided in this question, with almost 20% never using ES6, over 10% using it exclusively, close to 30% using it extensively and almost 40% using it occasionally.

受訪者在這個問題上的反應至關分歧，有近 20% 的人幾乎從不使用 ES6，超過 10% 的人只寫 ES6，接近 30% 的人普遍使用 ES6，近 40% 的人偶爾使用。

Do you know what’s coming in ES2016?

你知道在即將到來的 ES2016 中會有什麼特性嗎？

Roughly speaking, half of the voters don’t know what’s coming in ES2016, while the other half have an idea of what’s coming next.

Over 60% of voters use Mac, while Linux and Windows users are close to 20% each.

超過 60% 的投票者使用 Mac，使用 Linux 和 Windows 的用戶都接近 20%。

How do you find reusable code, libraries and tools?

你是經過哪一種方式搜索到可重用的代碼、庫和工具的？

Respondents seem to favor GitHub and search engines, but there’s also a healthy dose of blogs, Twitter, and the npm website being consumed.

Unsurprisingly, the top-notch Mozilla Developer Network is leading the pack in terms of JavaScript documentation and news. JavaScript Weekly is also a very popular source of news and articles at almost 40% of respondents.

不出所料地，Mozilla 開發者網絡 在 Javascript 文檔和新聞方面處於領先地位。JavaScript 週刊 也是一個很是受歡迎的新聞和文章的直接來源，它有着超過 40% 的投票。

Which of these features have you heard about?

你據說過下面哪些新特性？

Over 85% of voters have heard about ServiceWorker, although I’d be curious to know how many of those have played around with it!

超過 85% 的人據說過 ServiceWorker，我很想知道這些人中有多少人使用過它。

What languages do you use primarily, besides JavaScript?

除了 JavaScript，你還主要使用哪些語言？

There’s so many languages to choose from, I was bound to forget a few, but the results speak for themselves.

這有太多的語言可供選擇，我確定會漏掉一些。可是結果不言自明。

Thanks!

謝謝

Lastly, I wanted to thank everyone who took part of the poll. It was far more popular than I anticipated and I’m looking forward to holding a similar poll next year. Hopefully, it’ll be one that’s even more diverse and perhaps a bit less biased.

最後，我想感謝參與這次調查的每個人。此次調查的受歡迎程度超出了個人預期，我很期待明年再進行一次相似的調查。我但願，那將會是一個更多樣性的，也許會再少一點傾向性的調查。
