TypeScript Foreach Loop

In TypeScript, there are two foreach loop types, for..of and for...in.

for...of is a standard foreach loop:

let cities: Array<string> = new Array<string>();
cities.push("Los Angeles");
cities.push("Seattle");

for (let city of cities) {
  console.log(city);
}

for..in is a specialized foreach loop used to list all properties of object, including inherited.
