On the string interpolation activity you can reference the array favourite_things by just using #{thing} for each one

There is no code showing how it is assigned? can someone help me out

the lesson should start with this code:

favorite_things = ["Ruby", "espresso", "candy"]

puts "A few of my favorite things:"

favorite_things.each do |thing|
  puts "I love " << thing << "!"

so its show how thing is assigned? .each has hopefully been taught, if not, surely it will come later.

It starts with the block parameter, |thing|, which acts as the iteration variable in the each loop. As the array is iterated, each element will in turn be assigned to thing which is interpolated in #{thing} within the output string expression.


If you are getting the right output but it’s not letting you move onto the next exercise check that you have not left a space before the ! because thats what was stopping me from being able to proceed.


dont seem to be winning

What is the expected output? And does that match with the output you see?

the expected output was identicle when asked for the solution

The expected output:

A few of my favorite things:
I love Ruby!
I love espresso!
I love candy!

your output:

A few of my favorite things:
["Ruby", "espresso", "candy"]
["Ruby", "espresso", "candy"]
["Ruby", "espresso", "candy"]

how are those the same/identical?

Ah! the syntax error kept saying it doesn’t say ‘I love Ruby’ then when i asked for the solution, it gave me the same output from my incorrect code that’s why i was confused.

Could you show me what the code looks like please? and thank you for such a prompt response, as I am a beginner to this language, soaking up as much as I can.

you where pretty close. you have the string ("I love #{things}!"), but you forget to print (puts`) the string.

aaaah man!! Thank you so much

It fails to say that you need an exclamation point. Who made this? So many errors.
