-You probably figured this one out (good job) — `toUpperCase()` is a type of String method. We’re passing an integer as the argument, thus we can’t call `toUpperCase()` on an integer.
+你可能已经发现了这个问题（干的漂亮） — `toUpperCase()` 是 String 的方法，我们将一个整型作为参数传递过去，显然无法调用整型的`toUpperCase()` 方法。


「显然无法调用整型的toUpperCase() 方法。」 => 「显然不能在整型上调用 toUpperCase() 方法。」

-The tuple expects the first value to be a `number` — but it’s not in this case, it’s a string `"Indrek"` and thus giving us an error.
+元组定义了第一个元素是 `number` 类型，但赋值时并不是 `number` 类型，而是一个值为 `"Indrek"` 的 `string` 类型。所以编译结果会报错。


第一个句号换成逗号吧

-Imagine tuples as organized arrays. You predefine the types in the correct order.
+元组就是组织好结构的数组，只是按照顺序定义好数组元素的类型

-In Typescript, you have to define the return type in your functions. Like so:
-There are functions which don’t have a `return` statement;
+在 TypeScript 中，你需要定义函数返回值的类型。因为有很多没有 `return` 语句的函数。

“感谢阅读，你很棒”读起来怪怪的，建议就写“感谢阅读！”。

@leviding 修改完成， @moods445 @goldEli 感谢校对。
认真考虑了下添加图片翻译的建议，本文主要想轻松的介绍下 TS，不适合引入太多文档的东西。
所以决定不翻译图片内容，请理解。
