interface MyInterface<T> { field: T } 这声明了一个接口,该接口具有一个属性字段,其类型由传递给 T 的类型确定。 对于类,语法几乎相同: class MyClass<T> { field: T constructor(field: T) { this.field = field } } 通用接口/类的一个常见用例是当您有一个字段,其类型取决于客户端代码如何使用接...
TypeScript Interface is a special entity that helps us create objects with certain properties. Let us proceed and create one. For instance, we can begin by typing the word Interface which is a reserved word in TypeScript to create a TypeScript Interface. Thus, when we create a TypeScript I...
Note, however, that the fact the classes aren’t exported means that the client code has no idea what the actual implementation is; all the client knows is that the Person interface defines three properties—firstName, lastName and fullName—and one method—greet—tha...

The functions defined inside a module that extends a module interface can be auto-inferred. And with this implementation, we have tree-shaking, because we can import only the functions we'll use. To do something similar today, we have to create a class or an object and export the whole ...
Excluding the type ofdefaultColorfrom being explored for inference means that"blue"never ends up as an inference candidate, and the type-checker can reject it. You can see the specific changes inthe implementing pull request, along withthe initial implementationprovided thanks toMateusz Burzyński!
需要注意的是接口的非函数成员类型必须完全一样，如下示例：复制代码interface Person {age: string;}interface Person {// TS2717: Subsequent property declarations must have the same type.// Property 'age' must be of type 'string', but here has type 'number'.age: number;}```在上面的例子中，...
