== Control flow == === Pattern Matching === Pattern matching is a powerful feature in Elixir that allows for complex data manipulation and conditional branching. It is used extensively in function clauses and case statements: Example: {status, message} = {:ok, "Success"} case response do {:ok, result} -> IO.puts("Result: #{result}") {:error, reason} -> IO.puts("Error: #{reason}") end === Conditional Expressions === Elixir provides if, unless, and case expressions for control flow based on conditions: Example: if condition do # do something else # do something else end unless condition do # do something else # do something else end case value do pattern1 -> # do something pattern2 -> # do something else _ -> # default case end
