题目我觉得可以改改，优化javascript条件语句的5个技巧

| At first glance, the above example looks good. However, what if we get more red fruits, say cherry and cranberries? Are we going to extend the statement with more || ? | ||

| 乍一看，上面的例子看起来不错。然而，如果我们得到更多的红色水果，比如樱桃和小红莓呢？我们要用更多的 || 来扩展这个表述吗？ |

如果我们得到更多水果，这里不看原文就有点突兀，因为get翻译为得到不妥
如果还有更多类型的水果需要判断呢

||
| Look at the example above, we want to print the fruit name if it's available or we will print unknown. We can avoid the conditional fruit && fruit.name checking with default function parameter & destructing. | ||

||
| 看看上面的例子，我们想打印水果名，如果它是可用的，或者我们将打印 unknown。我们可以避免使用与默认函数参数和解构对条件 fruit && fruit.name 进行检查。 |
|
|
||
| Much cleaner now right? In a similar way, if we want to test if any of the fruit is red, we can use `Array.some` to achieve it in one line. | ||

| 现在干净多了，对吧？类似地，如果我们想测试任何一个水果是红色的，我们可以使用 `Array.some` 来实现它在一行。 |
