By definition, string interpolation is a practice used to join two strings together in a new object. An interpolated string is wrapped in the # function, as well as curly brackets.
Here’s an example of Elixir string interpolation :
x = "Apocalypse"
y = "X-men #{x}"
IO.puts(y)
x = "Apocalypse"
y = "X-men #{x}"
IO.puts(y)​
