連番の数字の配列を作成(es2015 ver)

Last updated at Posted at 2016-09-11

tl;dr (追記)

// 0始まりでよいなら・・・
const minitues = [...Array(60).keys()]
// => [0, 1, 2, 3,....,59]

// 1始まりにしたい、etc.なら・・・・
const minitues = [...Array(60).keys()].map(i => ++i)
// => [1, 2, 3, 4,....,60]
  • コメント欄で教えてもらったやつ。
  • コメント主が退会して表示されなくなったため転記

例えば 0,1,...,59と続く配列がほしいなら

const minitues = Array.from(new Array(60)).map((v,i) => i)
// [0, 1, 2, 3,....,59]
  • (new Array(60)).map(...)だとうまくいかない

1から始めたいなら

const minitues = Array.from(new Array(60)).map((v,i)=> i + 1)

coffeescriptだと。。。

minitues = [0...60]
