去掉字符串中每隔一个单词的算法？

function removeEveryOtherWord(str) {
  const words = str.split(' ');
  const result = [];
  let count = 0;

  for (let i = 0; i < words.length; i++) {
    if (count % 2 === 0) {
      result.push(words[i]);
    }
    count++;
  }

  return result.join(' ');
}

const input = "This is a sample string to test the algorithm";
const output = removeEveryOtherWord(input);
console.log(output);
