在JavaScript数组中将连续数字分组为"from~to“字符串

function groupNumbersToRange(array) {
  let result = [];
  let start = array[0];
  let end = array[0];
  
  for (let i = 1; i < array.length; i++) {
    if (array[i] - array[i-1] !== 1) {
      let range = start === end ? start.toString() : start.toString() + '~' + end.toString();
      result.push(range);
      start = array[i];
    }
    end = array[i];
  }
  
  let range = start === end ? start.toString() : start.toString() + '~' + end.toString();
  result.push(range);
  
  return result;
}

// 示例用法
let array = [1, 2, 3, 5, 6, 8, 9, 10, 12];
let result = groupNumbersToRange(array);
console.log(result); // 输出: ['1~3', '5~6', '8~10', '12']
