先提交一下,看下中间有没有什么错误或不标准的地方好及时修改.

huluoyang · 2018-07-20T03:55:53Z

全角符号和半角符号混用的问题，比较常见，望今后注意。

S1ngS1ng

翻译中请使用全角标点，且全角标点之后不应由多余的空格
如果 <code></code> 之后是中文字符，那应该添加空格；但如果是标点则不应添加
记得加上代码示例中注释部分的翻译

@huluoyang @wudifeixue 建议所有的关键字都加上 <code></code> 你们觉得呢？

请把逗号改成全角的。下同

另外，这一行是引出下文的，建议结尾用冒号 ：

-        "Because this behavior does not throw an error, searching and fixing bugs becomes more difficult.<br>",

原文 As you can see in the code above，这里的 see 不需要特意地翻译出来。
可以说 在上面的代码中， 或者 上面的代码

标点问题也请修改一下

建议这里不用“最初声明为”，改用“初始值为”

既然是字符串，个人建议这里写成 <code>'James'</code> 和 <code>'David'</code>
效果图：

就可能会在你不经意的时候产生变量的覆盖 建议改成：
就可能会在不经意间覆盖了之前定义的变量。

注意结尾的句号

两种说法：

这样的行为不会报错导致了 debug 非常困难。

因为这样的行为不会报错，所以当它出现时，debug 会非常困难。

你来决定吧

-        "As you can see, <code>printNumTwo()</code> prints 3 and not 2.

The <code>let</code> keyword does not follow this behavior:",
+        "可以看到, <code>printNumTwo()</code> 打印了 3 而不是 2。 这是因为 <code>i</code> 发生了改变,并且函数 <code>printNumTwo()</code> 返回的是全局变量 <code>i</code>的值,而不是 for 循环中创建函数时 <code>i</code> 的值。The <code>let</code> 关键字就不会有这种现象:",


迷之 The 😂

-        "<code>i</code> is not defined because it was not declared in the global scope.

+        "<code>i</code> 在全局作用域中没有声明,所以它没有被定义, 它只会在 for 循环的语句中被声明。 因为在循环语句中的 <code>let</code>关键字创建了拥有独一无二的值 (0, 1, 或 2) 的三个不同 <code>i</code> 变量,所以 <code>printNumTwo()</code> 返回了正确的值。",


建议在不影响意思的前提下，尽量调整为主动语态。 @huluoyang

它只会在 <code>for</code> 循环的语句中被声明 => 它的声明只会发生在 <code>for</code> 循环内。

因为在循环语句中的 <code>let</code>关键字创建了拥有独一无二的值 (0, 1, 或 2) 的三个不同 <code>i</code> 变量 建议改成：
在循环执行的时候，<code>let</code> 关键字创建了三个不同的 <code>i</code> 变量，他们的值分别为 0、1 和 2

个人觉得这里补充说明一下可能会更好

-        "Fix the code so that <code>i</code> declared in the if statement is a separate variable than <code>i</code> declared in the first line of the function. Be certain not to use the <code>var</code> keyword anywhere in your code.",
-        "This exercise is designed to illustrate the difference between how <code>var</code> and <code>let</code> keywords assign scope to the declared variable.

+        "这个练习说明了使用 <code>var</code> 与 <code>let</code>关键字声明变量时,作用域之间的不同。当编写类似这个练习中的函数的时候,通常来说最好还是使用不同的变量名,用于避免困惑。"


使用不同的变量名,用于避免困惑。 建议改成：
使用不同的变量名来避免误会。

在 if 语句中声明的 <code>i</code> 变量的值是 \"block scope\"。 建议改成：

S1ngS1ng · 2018-07-25T04:35:17Z

@demongodYY desc、tests 的肯定要。files 里面翻译注释的部分，如果注释对做题是有帮助的。
use strict; 是 JS 关键字。https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode

wudifeixue · 2018-07-30T06:21:23Z

建议所有的关键字都加上<code></code>这个我不觉得是好事儿，这个一定要根据题来决定，我和我弟正在刷题能看到很多问题，但是关键字都加上<code></code>可以肯定不是好的选择。

demongodYY · 2018-07-30T09:21:40Z

@S1ngS1ng 所以是要重新提个 PR 吗？ T_T

S1ngS1ng · 2018-07-30T18:08:59Z

@demongodYY 可以的，不会很麻烦。

# 获取 upstream 的 HEAD 指针
git fetch upstream

# 基于 upstream 的 translate branch 新建一个 branch
git checkout -b translate-es6 upstream/translate

# 由于你这个 PR 是基于你的 translate branch 开的，
# 所以把这个 branch 上属于你的文件改动应用到新的 branch 上
git checkout translate -- 02-javascript-algorithms-and-data-structures/es6.json
git checkout translate -- 02-javascript-algorithms-and-data-structures/es6.md

# 这个应该只输出你改过的两个文件才对
git status

# add、commit、push
git add .
git commit -m "Finish translation of ES6"
git push origin translate-es6

# 然后用这个新的 branch 再开 PR 就好了

上面显示你改了 60 多个文件，显然是不准确的嘛。
记得以后用 pull --rebase，就不会出现这样的问题了
