vue的单文件组件.vue里使用ts报这种错，你可以试着把vscode底下的那个蓝条上面的语言模式改成vue，而不是HTML，这样就不报错了

Pro TypeScript. Application-Scale JavaScript Development Steve Fenton page 300 TypeScript is a language created and maintained by Microsoft, and released under an open-source Apache 2.0 License (2004). The language is focused on making the development of JavaScript programs scale to many thousands of lines of code. In fact, Microsoft has written both the Azure Management Portal (1.2 million lines of code) and the Visual Studio Code editor (300,000 lines of code) in TypeScript. The language attacks the large-scale JavaScript programming problem by offering better design-time tooling, compiletime checking, and dynamic module loading at runtime. As you might expect from a language created by Microsoft, there is excellent support for TypeScript within Visual Studio, but plenty of other development tools have also added support for the language, including VS Code, WebStorm, Eclipse, Sublime Text, Vi, Atom, IntelliJ, and Emacs among others. The widespread support from these tools as well as the permissive open-source license makes TypeScript a viable option outside of the traditional Microsoft ecosystem. The TypeScript language is a typed superset of JavaScript, which is compiled to plain JavaScript in the flavor of your choosing. This makes programs written in TypeScript highly portable as they can run on almost any machine — in web browsers, on web servers, and even in native applications on operating systems that expose a JavaScript API, such as WinJS. The language features found in TypeScript can be divided into three categories based on their relationship to JavaScript (see Figure 1). The first two sets are related to versions of the ECMA-262 ECMAScript Language Specification, which is the official specification for JavaScript. The ECMAScript 5 specification forms the basis of TypeScript and supplies the largest number of features in the language. Subsequent versions of the ECMAScript specification are rolled into TypeScript releases, often as early previews that fe
