Trouble with array syntax below in html.erb file. <html> <head>   <title>Ruby Arrays</title> </head> <body>     <%= array = ['a','b','c'] %> </body> </html>

Shows up in browser as this: ["a", "b", "c"]

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.
