One Game Is Not Enough! 🔁

One round is fun, but who wants to play just once? Nobody! 😄

Let's make the game play again and again using a loop! 🔄

console.log('Round 1! 🎮')
console.log('Round 2! 🎮')
console.log('Round 3! 🎮')

What is a Loop? 🌀

A loop repeats code many times so you don't have to copy-paste! 🌀

Imagine telling your robot "do this 5 times" instead of saying it 5 times. 🤖

console.log('A loop repeats things! 🔁')
console.log('Super handy! ✨')

The for Loop 🔢

A for loop counts for us! 🔢

It starts at a number, keeps going while a rule is true, and adds 1 each time.

for (let i = 1; i <= 3; i++) {
  console.log('Count: ' + i + ' 🔢')
}

Playing 3 Rounds 🎮

Let's use the loop to play 3 rounds of the game! 🎮

Each time through, it's a new round. 🔄

for (let round = 1; round <= 3; round++) {
  console.log('--- Round ' + round + ' ---')
  console.log('Playing! 🎲')
}

Adding the Picks 🤖

Inside each round, the computer makes a fresh pick! 🤖

Let's add our random picker to the loop. 🎲

let choices = ['rock', 'paper', 'scissors']
for (let round = 1; round <= 3; round++) {
  let comp = choices[Math.floor(Math.random() * 3)]
  console.log('Round ' + round + ': computer picked ' + comp + ' 🤖')
}

Keeping Score 🏅

Let's count how many times you win! We make a score box and start it at 0. 🏅

Each win adds 1!

let score = 0
score = score + 1
score = score + 1
console.log('Your score: ' + score + ' 🏅')

Score Inside the Loop 📈

Now we keep score across all the rounds! 📈

The score box remembers wins from round to round. 🧠

let score = 0
for (let round = 1; round <= 3; round++) {
  score = score + 1
  console.log('Round ' + round + ': win! Score = ' + score + ' 🏅')
}

The while Loop 🔄

Another loop is the while loop. It keeps going while something is true! 🔄

Great for "keep playing until 3 wins". 🎯

let wins = 0
while (wins < 3) {
  wins = wins + 1
  console.log('Win number ' + wins + '! 🎉')
}
console.log('Got 3 wins! 🏆')

Stop the Loop 🛑

Sometimes we want to STOP early. We use break to jump out of the loop! 🛑

Like stopping the game when someone wins big. 🏆

for (let i = 1; i <= 10; i++) {
  console.log('Round ' + i)
  if (i === 3) {
    console.log('Game over! 🛑')
    break
  }
}

The Full Game Loop 🎉

Let's put it ALL together: loop, computer pick, and score! 🎉

This is your very own Rock Paper Scissors game! 🕹️

let choices = ['rock', 'paper', 'scissors']
let score = 0
for (let round = 1; round <= 3; round++) {
  let comp = choices[Math.floor(Math.random() * 3)]
  console.log('Round ' + round + ': computer ' + comp)
  score = score + 1
}
console.log('Final score: ' + score + ' 🏆')

You Built the Whole Game! 🕹️

Incredible! You made a full game that plays again and again! 🎉

for loop counts rounds 🔢
while loop keeps going 🔄
break stops early 🛑
A score box keeps points 🏅

console.log('You built the game! 🕹️')
console.log('You are a coder! 🌟')
