TypeScript - Loops & Arrays

Creating Loops & Arrays:
* Loop is used to iterate some values.
Eg 1.
for (let i=0; i < 5; i++) {
    console.log(i);
}
Eg.2: Find the average from the integer array.
let reviews: number[] = [5, 5, 4.5, 1, 3];

let total: number = 0;

for (let i=0; i < reviews.length; i++) {
    console.log(reviews[i]);
    total += reviews[i];
}

let average: number = total / reviews.length;
console.log("Review average = " + average);

* Array is Growable in Typescript.
Eg.1
let sportsTwo: string[] = ["Golf", "Cricket", "Tennis"];

sportsTwo.push("Baseball");
sportsTwo.push("Futbol");

for (let tempSport of sportsTwo) {
    console.log(tempSport);
}
