怎么运行Typescript

依据官方示例：

npm i -g typescript

示例：tsc *.ts

实例：tsc hello.ts

不过以上实现的太有限制了，如下实现可满足正常测试以及学习使用

package,json

 {
     "name": "TypeScript",
     "version": "1.0.0",
     "description": "",
     "main": "index.js",
     "scripts": {
         "test": "echo \"Error: no test specified\" && exit 1",
         "start": "concurrently \"npm run tswatch\" \"npm run lite\"",
         "tsc": "tsc",
         "tswatch": "tsc -w",
         "lite": "lite-server"
     },
     "dependencies": {
         "core-js": "2.5.7",
         "classlist.js": "1.1.20150312",
         "systemjs": "0.21.4",
         "bootstrap": "4.1.3"
     },
     "devDependencies": {
         "concurrently": "^3.6.1",
         "lite-server": "^2.4.0",
         "typescript": "^2.9.2",
         "typings": "^2.1.1"
     },
     "keywords": [],
     "author": "",
     "license": "ISC"
 }

tsconfig.json

 {
     "compilerOptions": {
         "target": "es5",
         "module": "commonjs",
         "moduleResolution": "node",
         "emitDecoratorMetadata": true,
         "experimentalDecorators": true,
         "lib": [
             "es2016",
             "dom"
         ]
     },
     "exclude": ["node_modules"]
 }

1.npm install

2.新建html文件,引入print.js，新建一个print.ts

3.npm start(执行完后会生成一个print.js文件,随后打开index.html，最后运行)
