I am using the SQLStorage from the Ionic platform. The remove function returns a promise. In my code I need to remove multiple values. When these are all finished I need to execute some code.

How can I wait for all of these and then execute a callback function?

Code:

removeAll() {    

  this.storage.remove(key1);

  this.storage.remove(key2);

  this.storage.remove(key3);    

}

Nesting all is a bad practise so I am looking for a decent solution :)

removeAll() {

  return this.storage.remove(key1).then(() => {

    this.storage.remove(key2).then(() => {

      this.storage.remove(key3);        

    });

  });

};
