How to convert the string value of one array to a character and transfer it to another array?

Question

ruby

Hello. I'm taking a course at codeacademy. I study Hashes and symbols. Can you please tell me why my code says "Oops, try again. It looks like you didn't add each symbolized string to the symbols array."?

strings = ["HTML", "CSS", "JavaScript", "Python", "Ruby"]

# Add your code below!

symbols = []
strings.each {|s|
    s.to_sym
    symbols.push(s)
}

Why you need to write like this:
symbols.push(s.to_sym)
What's the difference?

Answer 1

Because it is to_symnot destructive, it returns a character, but does not change the initial value of the variable.

Answer 2

symbols = strings.map(&:to_sym)
