How to convert a String to an Array?

Ruby

Is there a way to convert a String to an Array? I could only find the
following -
‘hello world’.scan(/./)

Thanks.

irb(main):001:0> “hello world”.split(//)
=> [“h”, “e”, “l”, “l”, “o”, " ", “w”, “o”, “r”, “l”, “d”]

I’m not sure if this is functionally the same or if there is some kind
of performance boost using split instead of scan.

And what’s the problem with that? Or do you want a different result?

Alternatively you can do

‘hello world’.split(’ ')

or

‘hello world’.split(/\s+/)

if you want to split on any number of whitespace chars.

If you want to split just on single spaces, your original solution is
faster.
