Instead of typing
name = "World" puts "Hello #{"World"}!"
I did it like this:
name = "World" puts "Hello" + name
Why is the #{} important, surely Im missing something

For example, it's easier to type out the first example then the second example in this script:
name = "Alex"
# Example 1
puts "Hello, #{name}! It's nice to meet you!"
# Example 2
puts "Hello, " + name + "! It's nice to meet you!"
Also, it's more understandable/more readable to use #{}.
An important note: In Ruby, there's two ways to create a string. One way is to wrap the string in single quotes ', and another way is to wrap the string in double quotes ". You only can use the #{} magic (called string interpolation) on double-quoted strings.
I hope this helps
Happy coding!
