Ionic Wait for Local Storage

I need to wait for the localStorage to retrieve a value before continuing my function... I read that I have to use "async/await" instructions but none of the examples I found really works.

My Code is

  _ajustes.EsPrimeraVez().then (async (promAjuste)=> {
    await console.log('TEST! en el then');
  });
  console.log('TEST! Post');

and inside "ajustes": 

public EsPrimeraVez() {
   console.log('TEST! entrando en primeravez');
   return this.storage.get('primeravez');

but it doesn't wait to the result to continue... is this possible? Thanks and happy new year to all!

Why are you using prmoise/then syntac if you want to wait to retrieve value from a function. Below code will run sequentially and once function is executed it will assign local storage value to variable 'mystoragevalue'. 

var mystoragevalue = _ajustes.EsPrimeraVez();
console.log('TEST! Post');

and inside "ajustes":

public EsPrimeraVez() {
   console.log('TEST! entrando en primeravez');
   return this.storage.get('primeravez');
}

Hope this helps...Happy coding...!!!
