transform 指的是从一个类型, 经过一个 transform process, 变成另一个类型. 这有点像RxJS stream中间一堆 pipe operator 那样. 看例子 //有个 Person Object Literal Typetype Person ={ str: string; num: number; };//我想搞一个 PromisePerson, 它拥有所有 Person 的属性, 只是类型变成 Promise<原本类...

ts只能构造一个匿名函数执行做到类似的事情，额外增加了一层性能损失5. rescript支持pipe operator，同样...
typescript program which works similar to that of object.keys in javascript where in typescript it would be the type of the object instead of taking the literal values which this operator returns the union type of all the properties of the object and to do this pipe operator ( | ) is ...
从这三个 Observable 的 pipe 内的 Operator 能看出这些操作之间的逻辑顺序。 这个ui5bootstrapped 返回的 Observable,什么时候被 subscribe 呢? 为什么触发点是 loadVisualization 的 subscribe 调用呢?loadVisualization 和 bootstrapUi5 的关联在哪里? 答案:loadVisualization返回的是this.viewportAdded$, 而this.viewpor...
