concatだらけになるtemplate literal - Qiita
Babelで変換されたあとのコードを見ると、一見無駄にも思えるコードが生成されていたのですが、実はそれが必要だった、というお話です。 Template Literalとは ES5までのJavaScriptでは、文字列を合成するには「1つ1つ+演算子で連結していく」「Array.prototype.joinで連結する」などの手法があったのですが、どちらの方法にしてもどのような構造の文字列ができるか、分かりづらいものでした。 ES6では、他言語のように文字列途中で式展開ができる、Template Literalが登場しています1。引用符として`...`を使い、式展開はその途中に${...}と書くという、他言語と比べてもそこまで違和感のない記法となっています。 Babelでの変換結果 で、例によってIEは非対応なので（MDN）、IEを切り捨てられない環境ではBabelでの変換が必要となります。こ

Automatically detect memory leaks with Puppeteer - Article by Christoph Guttandin - Media Codings
About half a year ago Bronley Plumb kindly made me aware of a memory leak in one of my open-source packages. To see this memory leak in action it was necessary to open a browser and its dev tools to execute some manual steps. On top of that, the memory had to be inspected manually. It was a complicated procedure. Normally I just add a failing test before I fix a bug. This time it was a bit more tr
Facebook’s open source browser contributions
Thanks to some powerful new technologies, web applications have come a long way in the past decade. But the performance of these web applications still lags behind that of their native counterparts. Like many complex applications on the web, our desktop Facebook.com website is slower to load than our native mobile Android app on the same hardware — even though the web app loads an order of magnitu
Stable Array.prototype.sort · V8
Show navigation Let’s say you have an array of dogs, where each dog has a name and a rating. (If this sounds like a weird example, you should know that there’s a Twitter account that specializes in exactly this… Don’t ask!) // Note how the array is pre-sorted alphabetically by `name`. const doggos = [ { name: 'Abby', rating: 12 }, { name: 'Bandit', rating: 13 }, { name: 'Choco', rating: 14 }, { na
