将 Array.map 与新的 Array 构造函数一起使用

我试图将 new Array() 构造函数与 map 一起使用，以便创建一个用于创建元素列表的单行代码.像这样:

I was trying to use new Array() constructor with map in order to create a one-line code that creates a list of elements. Something like this :

let arr = new Array(12).map( (el, i) => {
  console.log('This is never called');
  return i + 1;
});

阅读文档，行为是有道理的.

Reading docs, the behaviour makes sense.

基本上文档说即使对于数组中声明的未定义值也会执行 map 的回调，但例如在创建空数组时不会像之前的代码那样.

Basically docs say that callback of map will be executed even for declared undefined values in array, but not for example when creating empty Arrays like the code before.

所以这应该有效:

var arr = new Array(12);

for(let i = 0; i < arr.length ; i++){
  arr[i] = undefined;
}

let list = arr.map( (e, i) => {
  console.log(i + 1);
  return i + 1;
});

所以，我们也可以这样做:

So, We also can do something like this :

let newArray = (length) => {
  let myArray = new Array(length);
  for(let i = 0; i < length; i++) myArray[i] = undefined;
  return myArray;
};

console.log( newArray(12).map( (el, i) => i + 1 ) );

所以我的问题.有没有更好/漂亮的方法来使用地图功能?

提前致谢！
