获取1-30组成的数组

Question

想获取的1到30的数字数组，记得es6有快捷的写法给忘了

Answer 1

Array.from({ length: 30 }, (_, index) => index + 1)

Answer 2

[...Array(31).keys()].slice(1)

range函数的写法是之前在某个回答里看到的

Answer 3

Array.from({length: 30}, (v, i) => i + 1);

参考MDN Using arrow functions and Array.from

Answer 4

Array.apply(null,{length:30}).map((v,i) => ++i)

Array.from({length: 30}, (v, i) => ++i)

Array(30).fill(1).map((v,i) => ++i)
