TypeScript，通过循环创建数组

// 使用for循环创建数组
function createArrayWithForLoop(length: number): number[] {
  const array: number[] = [];
  for (let i = 0; i < length; i++) {
    array.push(i);
  }
  return array;
}

// 使用while循环创建数组
function createArrayWithWhileLoop(length: number): number[] {
  const array: number[] = [];
  let i = 0;
  while (i < length) {
    array.push(i);
    i++;
  }
  return array;
}

// 使用do-while循环创建数组
function createArrayWithDoWhileLoop(length: number): number[] {
  const array: number[] = [];
  let i = 0;
  do {
    array.push(i);
    i++;
  } while (i < length);
  return array;
}

// 示例调用
const length = 5;
const array1 = createArrayWithForLoop(length);
const array2 = createArrayWithWhileLoop(length);
const array3 = createArrayWithDoWhileLoop(length);
console.log(array1); // [0, 1, 2, 3, 4]
console.log(array2); // [0, 1, 2, 3, 4]
console.log(array3); // [0, 1, 2, 3, 4]
