If I run the initial code even before adding to it, it gives out warning:

(test):10: warning: found = in conditional, should be ==

How crucial is it?

Not the best of instructions for this exercise; in fact they were a bit misleading. In step 3, instead of saying:

  1. For each s in strings , use .to_sym to convert s to a symbol and use .push to add that new symbol to symbols .

They should’ve said for each ‘s’ push it to symbols and then convert each string to symbol using .to_sym

I was getting the same error as you.

I’m getting the same error as well. I have

strings = [“HTML”, “CSS”, “JavaScript”, “Python”, “Ruby”]

Add your code below!

symbols =
strings.each do |s|

puts symbols

I tried to push it first and get the same error?

The conversion to symbol should take place before pushing it to the symbols array.

strings.each do |s|
    t = s.to_sym

I don’t believe the instructions are misleading, but I don’t like the format of the .each used in the example. What I wrote and succeeded with is below.

symbols = []

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

print symbols

Why ‘hate’ when they are both valid. Learners should know how to do both, and not get fixated or biased toward one in favor of another. We start them out with do..end, and let them get comfortable with the syntax, then work them into block syntax. I’m sure that’s how I learned this stuff, way back when.

I’m merely stating my preference. If ‘hate’ is too strong a word to use here, I have edited my post.
