用来在定义 Vue 组件时为 TypeScript 提供类型推导的辅助函数。 对于一个 ts 文件,如果我们直接写 export default {},无法有针对性的提示 vue 组件里应该有哪些属性。 但是,增加一层 defineComponet 的话,export default defineComponent({}),就可以对参数进行一些类型推导和属性的提示等操作。 functiondefineComponent...
这个子类当时可能是work的，因为Babel 6、TypeScript都使用了[[Set]]语义。

In Typescript you can do this: export class Company { constructor( public id: number = 0, public name: string = '', public shortName: string = '' ) {} } const company1 = new Company(); console.log(company1); The above snippet will help you to set the default values even if ...
prototype, key, { get: function () { return SourceObject[key] }, enumerable: true, configurable: true }) }) } interface IForm { name: string; label: string; value: any; sequence: number; width: number; type: number; } class Form { constructor(form: IForm) { defineGetter(form, Form...
所以第一步需要从 StringConstructor/ NumberConstructor 等 xxConstrucror 中得到对应的类型 string/number 等。可以通过 infer 来实现 type a = StringConstructor type ConstructorToType = T extends { (): infer V } ? V : never type c = ConstructorToType // type c = String 复制代码 上面我们通过 ...
