TypeScript

注意编译Typescript项目之前需要确保安装了node.js

编译.ts文件项目需要打开终端输出tsc index.ts 之后会生成一个index.js文件

// //ts中创建接口使用interface
interface Person {
    firstName: string
    lastName: string
}

function person(person: Person) {
    return `my name is ${person.firstName}${person.lastName}`
}
let user: Person = {
    firstName: "wu",
    lastName: "huiluo"
}
console.log(person(user))

接下来我们可以声明一个User类来代替let user

//声明一个类
class User {
    fullName: string
    firstName: string
    lastName: string
    constructor(firstName: string,lastName: string) {
        this.firstName = firstName
        this.lastName = lastName
        this.fullName = firstName + '' + lastName
    }
}

最终代码

//声明一个类
class User {
    fullName: string
    firstName: string
    lastName: string
    constructor(firstName: string,lastName: string) {
        this.firstName = firstName
        this.lastName = lastName
        this.fullName = firstName + '' + lastName
    }
}
// //ts中创建接口使用interface
interface Person {
    firstName: string
    lastName: string
}

function person(person: Person) {
    return `my name is ${person.firstName}${person.lastName}`
}
let user = new User('wuhui','luo')
console.log(person(user))

在终端中运行ts程序

程序执行结果完美兼容了User类和Person类
