That’s perfectly valid. [“a”, “b”, “c”] is the same as [‘a’, ‘b’,
‘c’]. That is, “a” is the same as ‘a’, and so on. (Unlike in some
languages, where only one or the other is used at all, or some where
it makes a difference in the type, such as C/C++, where ‘a’ would be a
character and “a” would be an array containing an ‘a’ and a null.)

When printing values out, Ruby represents strings using double quotes
instead of single as you used. Ruby doesn’t remember (or care) which
you used, once it determines the actual value of the string.

The only time it matters is when you are writing a string; single
quotes prevent variables and other “magic strings” taking on their
values. For example, try this in irb:

x = 3
=> 3

‘x is #{x}’
=> “x is #{x}”

“x is #{x}”
=> “x is 3”

y = “foo”
=> “foo”

z = ‘foo’
=> “foo”

y == z
=> true

May be He wants to access the content of the array like this:

array[0] #1
array[1] #2
array[2] #3

Here’s how to access the content of the array using .each:

array = [‘a’,‘b’,‘c’]
array.each do|x|
puts x
end

results
a
b
c

That’s not going to work in his .erb file is it, as ‘puts’ is going to
write to the console.

If the OP actually asks a question, we’ll know what he wants to do
with his array rather than taking random stabs in the dark.
