首先，您将学习使用TypeScript使用create-react-app引导应用程序。 然后，您将学习使用React和TypeScript(包括样式化组件)来构建项目。 测验问题将来自琐事API。 您将学习如何将API与React结合使用。

Using Typescript can help make sure your variables and props are what you intend since it evaluates your code during compile-time (as opposed to run-time). This becomes especially important as your program becomes larger.

使用Typescript可以帮助确保您的变量和prop是您想要的，因为它在编译时(而不是运行时)评估代码。 随着您的程序变大，这变得尤为重要。
