飛ばし読み

飛び数え！⏭️

まずは1ずつ数えましょう 1️⃣

for (let i = 1; i <= 5; i = i + 1) {
  console.log(i);
}

今度は2ずつ跳びましょう！🐰

for (let i = 2; i <= 10; i = i + 2) {
  console.log(i);
}

これが偶数です！✅

console.log('Skip by 2 makes even numbers:');
for (let i = 2; i <= 12; i = i + 2) {
  console.log(i + ' ✅');
}

5ずつ飛びましょう！🖐️

for (let i = 5; i <= 25; i = i + 5) {
  console.log(i);
}

10ずつ飛びましょう！🔟

for (let i = 10; i <= 50; i = i + 10) {
  console.log(i);
}

飛び数えマシン 🛠️

function skipCount(step) {
  for (let i = step; i <= step * 5; i = i + step) {
    console.log(i);
  }
}
console.log('Counting by 3:');
skipCount(3);

いろいろな刻み幅を試しましょう 🎚️

function skipCount(step) {
  for (let i = step; i <= step * 5; i = i + step) {
    console.log(i);
  }
}
console.log('Counting by 4:');
skipCount(4);

数を1行に並べましょう 📏

let numbers = [];
for (let i = 5; i <= 30; i = i + 5) {
  numbers.push(i);
}
console.log('Counting by 5: ' + numbers.join(', '));

pushでリストに追加します ➕

let numbers = [];
for (let i = 2; i <= 20; i = i + 2) {
  numbers.push(i);
}
console.log('Even numbers: ' + numbers.join(', '));

飛び数えができます！🏆
