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

3

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 << "!"
end

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

4

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

7

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

8

the expected output was identicle when asked for the solution

9

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.

11

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.

12

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

13

aaaah man!! Thank you so much

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