Array way

[WaKeMaTTa]

Hello,

which is the difference between:

a = *(1..3)
# => [1, 2, 3]

and this:

a = (1..3).to_a
# => [1, 2, 3]

---

And which is accepted? And there is another way more readable?

This is a good question and one that I've wondered about myself. I asked some of the rubyists I know and they opted for:

a = (1..3).to_a

for readability reasons.

Also .to_a is a faster operation.

So, .to_a is faster and more explicit.

Indeed. I'd definitely go for .to_a over using the splat operator in this situation. Always optimize for readability!
