Implement the built-inReturnType<T>generic without using it. For example constfn=(v:boolean)=>{if(v)return1elsereturn2}typea=MyReturnType<typeoffn>// should be "1 | 2" /* ___ Your Code Here ___ */typeMyReturnType<Textends(...args:any[])=>any>=Textends(...args:any[])=>...
泛型委托等等。在使用泛型的时候，它们会自行检测你传入参数的类型，因此它可以为我们省去大量的时间，不...
For those who prefer specifying the element type as a generic parameter instead of casting, you can add a declaration by creating a "Document.d.ts" anywhere under the TypeScript project folder and using the following code. export { }; declare global { interface Document { getElementById<E ...

ThatreportErrorcall there isn't happy. Specifically it's theerror.messagebit. It's because (as of recently) TypeScript defaults ourerrortype tounknown. Which is truly what it is! In the world of errors, there's not much guarantees you can offer about the types of errors that are thrown...
ref 最大的特点是什么?需要 .value 取到的才是实际值,不然取的只是包装对象而已。所以你这里应该打印的是:console.log(obj.testObj.value.a);P.S. 如果你用的是 TypeScript,此时 IDE 已经会给你报错了,你就直接明白了。所以你看 TypeScript 在这种时候是不是很有用?让你少走很多 Debug 弯路。
