Can not pass variable from method to the test - protractor

I am writing a test checking for the amount of gold I have. I am using typescrypt and protractor.

I have a method GetAmoutOfChips:

public static GetAmountOfChips(): PromiseLike<any> {
    let chips: number = 1;
    NavigateTo.myProfile();
    browser.sleep(900);
    let promise = MyProfile.Basic.chipsAmount.getText().then((chipAmount) => {
        chips = parseInt(chipAmount);
        console.log("+++++++++++1" + chips);
    });
    MyProfile.Basic.close.click();
    console.log("+++++++++++2" + chips);
    return promise;
}

I would like to use it in a test. So I am doing the following: 

Actions.Basic.GetAmountOfChips().then((chipAmount: number) => {
            chipsBalance = chipAmount;
            console.log("+++++REAL" + chipsBalance);
        });

console.log#1 returns the value i want to use. console.log#2 returns undentified. So I can not pass the variable to the test. What do i do to pass the variable from the method to the test?

You have to do everything inside the then. You can also return the value there to create another promise.

public static GetAmountOfChips(): PromiseLike<any> {
    NavigateTo.myProfile();
    browser.sleep(900);
    let promise = MyProfile.Basic.chipsAmount.getText().then((chipAmount) => {
        // this is executed asynchronously
        MyProfile.Basic.close.click();

        // return a value to create another promise        
        return parseInt(chipAmount);

    });

    return promise;
}

Promises can be quite confusing, you can find out more here.

In your test you must also do the checks in the then function.

Actions.Basic.GetAmountOfChips().then((chipAmount: number) => {
  // test here not outside 
  expect(chipAmount).toBe(10);
});
