Rows of Emojis! 🔁

Welcome back, emoji artist! 🌟 Last time we printed single emojis. 😄

Today we use a loop to repeat emojis and make rows! 🔁 Super fun!

What is a Loop? 🔄

A loop repeats an action many times so you don't have to type it over and over! 🔄

Perfect for printing lots of emojis! 🎉

for (let i = 0; i < 3; i++) {
  console.log('🎈');
}

Counting With the Loop 🔢

The loop counts from 0 up to a number. 🔢

i < 5 means it repeats 5 times. Let's print 5 stars! ⭐

for (let i = 0; i < 5; i++) {
  console.log('⭐');
}

Building a Row ➡️

Instead of one per line, let's build a row in a box! ➡️

We add an emoji each loop, then print at the end. 🪄

let row = '';
for (let i = 0; i < 5; i++) {
  row = row + '🍎';
}
console.log(row);

A Longer Row 📏

Want more emojis? Just change the number! 📏

Let's make a row of 10 fish! 🐠

let row = '';
for (let i = 0; i < 10; i++) {
  row = row + '🐠';
}
console.log(row);

Rows With Spaces 〰️

Add a space between emojis to spread them out! 〰️

It makes the row easier to see. 👀

let row = '';
for (let i = 0; i < 6; i++) {
  row = row + '🌸 ';
}
console.log(row);

Many Rows 📚

Print several rows by looping again! 📚

Each loop makes a new line of emojis. 🎊

for (let i = 0; i < 3; i++) {
  console.log('🐶🐶🐶🐶');
}

An Emoji Counter 🔢

The loop number can be part of the message! 🔢

Let's show which star we are printing. ⭐

for (let i = 1; i <= 4; i++) {
  console.log('Star number ' + i + ' ⭐');
}

A Row Machine 🤖

Let's build a function that makes any emoji row! 🤖

Tell it the emoji and how many. It does the rest! 🎉

function emojiRow(emoji, count) {
  let row = '';
  for (let i = 0; i < count; i++) {
    row = row + emoji;
  }
  console.log(row);
}
emojiRow('🍕', 6);

Use Your Row Machine 🎛️

Now make all kinds of rows easily! 🎛️

Just call the machine with different emojis and numbers! 🤩

function emojiRow(emoji, count) {
  let row = '';
  for (let i = 0; i < count; i++) {
    row = row + emoji;
  }
  console.log(row);
}
emojiRow('🌟', 8);
emojiRow('🐝', 4);
