In the code above, we have a name collision because we already have a class with the name User and we also have a TypeScript Interface with the same name i.e. User. For some reason, we need to specify that this is specifically a TypeScript Interface and not a class. There are two ...
name: string; } interface User extends Name { age: number; }//4、type extends interfaceinterface Name { name: string; } type User= Name &{ age: number; } 7.2、不同点 type 可以而 interface 不行 type 可以声明基本类型别名,联合类型,元组等类型 //基本类型别名type Name =string//联合类型int...

我认为进行类型论证会很好,所以在src/shims-vue.d.ts中,就像下面的一个一样,我尝试添加它,但仍然得到了错误。 declare module 'vue/types/vue' { interface Vue { registerBackButtonCallback: () => void } } 有人试过在vue3组件中使用脚本lang=“ts”调用全局混合的方法吗? 非常感谢你的建议。
interface是JavaScript中的“未来保留关键字”。Javascript不允许将其用作标识符，以便可以将其用作关键字...
