TS 从 0 到 1 - 类型进阶

{ vType: "motorcycle"; // 可辨识 make: number; } interface Car { vType: "car"; // 可辨识 transmission...: CarTransmission; } interface Truck { vType: "truck"; // 可辨识 payloadPounds: number; } Motorcycle...、Car、Truck 都有一个 vType 属性，它们的值分别是 "motorcycle"、"car"、"truck"，这就是可辨识属性，其他的属性只跟特性的接口有关。...联合类型 type Vehicle = Motorcycle | Car | Truck; 类型守卫 const EVALUATION_FACTOR = Math.PI; function evaluatePrice...因为在 Motorcycle，Car，Truck 中都有 vType 属性，但是 Motorcycle 中没有 payloadPounds 属性，所以 evaluatePrice 函数中的 vehicle.payloadPounds

TypeScript 可辨识联合类型

可辨识要求联合类型中的每个元素都含有一个单例类型属性，比如： enum CarTransmission { Automatic = 200, Manual = 300 } interface Motorcycle...{ vType: "motorcycle"; // discriminant make: number; // year } interface Car { vType: "car";...二、联合类型基于前面定义了三个接口，我们可以创建一个 Vehicle 联合类型： type Vehicle = Motorcycle | Car | Truck; 现在我们就可以开始使用 Vehicle...Property 'capacity' does not exist on type 'Motorcycle'....原因是在 Motorcycle 接口中，并不存在 capacity 属性，而对于 Car 接口来说，它也不存在 capacity 属性。那么，现在我们应该如何解决以上问题呢？
