Export value [object Promise] use angular 8?

问题

My code

async loginStatus() { 
  return new Promise((resolve) => {
     firebase.auth().onAuthStateChanged(firebaseUser => resolve(firebaseUser))
  })
}
async checkLoginStatus(){
  const userObject = await this.loginStatus()
  return  userObject    
}

How export value don't use this syntax

this.checkLoginStatus().then(e => console.log(e));

or how save value in a variable .

output if not this syntax => checkLoginStatus[object Promise]

回答1:

make your method async. lets say you was doing it in a method name storeValue(). Do it like :-

async storeValue() {
   const output = await this.checkLoginStatus();
}
