-ES2015 introduced many new features to the JavaScript language, including significant improvements to the regular expression syntax with the Unicode (`/u`) and sticky (`/y`) flags. But development has not stopped since then. In tight collaboration with other members at TC39 (the ECMAScript standards body), the V8 team has proposed and co-designed several new features to make regular expressions even more powerful.
+ES2015 给 JavaScript 语言引入了许多新特性，其中包括正则表达式语法的一些重大改进，新增了 Unicode （`/u`） 和粘滞位 （`/y`）两个修饰符。但从那以后，发展从未止步。经过与 TC39（ECMAScript 标准委员会）的其他成员的紧密合作，V8 团队提议并共同设计了让正则表达式更强大的几个新特性。


但从那以后，发展从未止步。

给人感觉像“在那之前，发展一直在止步”，建议改成 ”而在那之后，发展也并未停止“

-These features are currently being proposed for inclusion in the JavaScript specification. Even though the proposals have not been fully accepted, they are already at [Stage 3 in the TC39 process](https://tc39.github.io/process-document/). We have implemented these features behind a flag (see below) in order to be able to provide timely design and implementation feedback to the respective proposal authors before the specification is finalized.
+这些新特性目前已经计划包含在 JavaScript 标准中。即使提案还没有完全通过，它们已经进入 [TC39 流程的候选阶段](https://tc39.github.io/process-document/)了。我们已经在一个 flag（见下文）之后实现了这些功能，以便在最终定稿之前提供及时的设计和实现反馈给各自的提案作者。


即使提案还没有完全通过，它们已经进入...

虽然...但是...

我们已经在一个 flag（见下文）之后实现了这些功能

我们已经在实现(更新?)完 flag (直接翻译成”修饰符“?)相关功能之后实现了这些特性

这里的 flag 不是修饰符，是指浏览器的实验功能

-Named captures are an upcoming feature that helps mitigate these issues by allowing developers to assign names to captures. The syntax is similar to Perl, Java, .Net, and Ruby:
+命名捕获是一个即将到来的特性，它允许开发者给捕获组分配名称来帮助缓解这些问题。语法类似于 Perl、Java、.Net 和 Ruby：


缓解这些问题

感觉怪怪的，要不译成 ”尽可能地解决这些问题“ ？

-The name already describes its meaning pretty well. It offers a way to restrict a pattern to only match if preceded by the pattern in the lookbehind group. It comes in both matching and non-matching flavors:
+名称已经很好地描述了它的意义。它提供一个方式来限制一个正则，只有后行组匹配通过之后才继续匹配。它提供匹配和非匹配两种选择：


名称已经很好地描述了它的意义

根据上下文补全：” “后行断言”这个名字已经很好地描述了它的涵义“
