node学习——Async+Await

const fs = require('fs');

const util = require('util');

const AsyncFile =util.promisify(fs.readFile)

asyncfunction init( ){

   try{

        let data =await AsyncFile ('./package.json');

        data =  JSON.parse( data );

        console.log(data.name); 

    }catch(err){

        console.log(err)

    }
