ES6-生成数字数组 [英] ES6 - generate an array of numbers

问题描述

为此，我找到了两个解决方案:

Having googled for it I found two solutions:

    var data = [...Array(10).keys()];
console.log(data);
    var data1 = Array(8).fill().map((_, i) => i);
console.log(data1);

data1显示[0，1，...，7]，但是数据仅显示[[object Array Iterator]]我如何实际看到数字.

data1 displays [0, 1, ..., 7] however data just displays [[object Array Iterator]] how do I actually see the numbers.

我需要它来进行一些数字上的迭代(Euler项目的一部分).

I need it for some iterations over numbers (part of Euler project).

以前，我在Python中做了很多Euler挑战.现在，我决定重新访问它，并在JS中尽我所能(尽可能多地使用ES6语法)来帮助我发展自己的JS技能.

Previously I did a lot of Euler challenges in Python. Now I decided I'll revisit it and do as much as I can in JS (as much ES6 syntax as possible) to help me develop my js skills.

推荐答案

这是在Codepen中工作的简单解决方案:

Here is a simple solution that works in codepen:

Array.from(Array(10).keys())

为清楚起见，Array.from()和Array.keys()需要ES6 polyfill才能在所有浏览器中工作.

To be clear, Array.from() and Array.keys() require an ES6 polyfill in order to work in all browsers.
