await returns pending promise

in this sample rez contains pending Promise. I need to get it resolved with other code paused till it's get resolved:

 function getCoordinates() {
    return new Promise(function (resolve, reject) {
        navigator.geolocation.getCurrentPosition(resolve, reject);
    });
}

async function getAddress() {
    await getCoordinates();
}
const  rez =  getAddress();
alert('wait for rez');

I know I can do something like getAddress().then(function () { alert('wait for rez')} ); but is there a way to continue not inside of then scope?

You need to await the async operation as well:

(async function(){
  function getCoordinates() {
      return new Promise(function (resolve, reject) {
          navigator.geolocation.getCurrentPosition(resolve, reject);
      });
  }

  async function getAddress() {
      await getCoordinates();
  }
   const rez = await getAddress();
   alert('wait for rez');
})()

As was commented functions wich calls promise needs to be async otherwise it returns pending promise. 

$(window).load(async function () {
    var rez = await getCoordinates();
    alert(rez.coords.latitude);});

function getCoordinates() {
    return new Promise(function (resolve, reject) {
    navigator.geolocation.getCurrentPosition(resolve, reject);
});};
