nodejs -- promise的返回

const a = async ()  => {
    return Sequelize.findAll({})   //这里返回一个promise，"aaaaa"也行
}

const b= async ()=>{
    const result =await a() ;     //这样就能拿到数据了

}

OR

const a = async ()  => {
    return new Promise((resolve,reject)=>{
        resolve(data)
    })
}

a().then((data)=>{
    console.log(data)  //拿到了数据
})

OR

const a= async ()=> {

    return "aaaaaa"
}


a().then((result)=>{
    console.log(result)
})

OR

const a = async ()  => {  
    return Sequelize.findAll({})   //这里返回一个promise  
}  
  
a().then(result=>{
    console.log(result)   //拿到了数据
})
