初始化一个typescript项目：

C:\Users\RS\Desktop\test\vue\typescript>tsc --init
message TS6071: Successfully created a tsconfig.json file.

编译并执行ts文件：

base-type.ts

let name: string = 'tdw'
let age: number = 12
let sen: string = `hello , my name is ${name}, i will be ${age + 1} years `

console.log(sen + name)

export {}

代码中添加export {}的原因： 如何在typescript中解决 error TS2451: Cannot redeclare block-scoped variable 'name'

执行：

C:\Users\RS\Desktop\test\vue\typescript>ts-node base-type.ts
hello , my name is tdw, i will be 13 years tdw
