首先下载typescript
npm i typescript
以下是greet.ts:
class User { fullName: string firstName: string lastName: string constructor(firstName:string, lastName:string) { this.firstName = firstName this.lastName = lastName this.fullName = firstName+' '+lastName } } interface Person { firstName: string lastName: string } let greeters = (person: Person) => { return 'hello '+person.firstName+'--'+person.lastName; } let user1 = new User('yee','hu') console.log(greeters(user1));在命令行输入:
tsc greet.ts(编译生成greet.js)
node greet.js(启动greet.js文件)
输出结果:
hello yee--hu
