単語を数えましょう！🔢

もう一度分割しましょう ✂️

let sentence = 'I love my dog';
let words = sentence.split(' ');
console.log(words);

リストの長さは？📏

let words = ['I', 'love', 'my', 'dog'];
console.log('Number of words: ' + words.length);

どんな文でも数えましょう 🎯

let sentence = 'coding is super fun';
let words = sentence.split(' ');
console.log('This sentence has ' + words.length + ' words! 🎉');

短い文で試しましょう 🐝

let sentence = 'hello world';
let words = sentence.split(' ');
console.log('Words: ' + words.length);

長い文で試しましょう 🦕

let sentence = 'the big brown bear ran up the tall green hill';
let words = sentence.split(' ');
console.log('This long sentence has ' + words.length + ' words!');

カウントマシンを作りましょう 🛠️

function countWords(sentence) {
  let words = sentence.split(' ');
  return words.length;
}
console.log(countWords('I am a coder'));
console.log(countWords('yes'));

マシンを使いましょう 🤖

function countWords(sentence) {
  return sentence.split(' ').length;
}
console.log('Words: ' + countWords('the cat sat on the mat'));
console.log('Words: ' + countWords('coding rocks'));

わかりやすい結果を表示しましょう 📊

function countWords(sentence) {
  let count = sentence.split(' ').length;
  console.log('📝 Your sentence: ' + sentence);
  console.log('🔢 Word count: ' + count + ' words!');
}
countWords('learning to code is awesome');

3つの文を数えましょう 📚

function countWords(sentence) {
  return sentence.split(' ').length;
}
console.log('A: ' + countWords('hi there'));
