Map 2 values from interface

I want to map 2 values from Interface:

export interface CurrenciesList {
  currency: string;
  country: string;
}

I want to map the result like this:

this.optionValues["currency"] = value.map(i => ({ id: i.currency, name: i.currency }));

But I would like to combine the result like this:

this.optionValues["currency"] = value.map(i => ({ id: i.currency, name: i.currency - i.country }));

But I get And as result. I would like to get this result into the list:

USD - United States

What is the proper way to map this: name: i.currency - i.country

You can try this. I am using ES6's template literals, if you are not familiar with this syntax. It can make string concatenation cleaner in some cases.

this.optionValues["currency"] = value.map(i => ({ id: i.currency, name: `${i.currency} - ${i.country}` }));
