在Javascript中组合多个值的数字范围

function generateRange(start, end) {
  var range = [];
  for (var i = start; i <= end; i++) {
    range.push(i);
  }
  return range;
}

var myRange = generateRange(1, 10);
console.log(myRange); // 输出 [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

function doubleRange(start, end) {
  var range = generateRange(start, end);
  var doubledRange = range.map(function(num) {
    return num * 2;
  });
  return doubledRange;
}

var myDoubledRange = doubleRange(1, 5);
console.log(myDoubledRange); // 输出 [2, 4, 6, 8, 10]
