Elixir Pattern Matching

Master pattern matching in Elixir to write elegant, declarative code. This skill covers function patterns, case statements, guards, and destructuring across various data structures.

Basic Pattern Matching

# Simple assignment is pattern matching
x = 1
1 = x  # This works because x matches 1

# Pattern matching with tuples
{:ok, value} = {:ok, "success"}
value  # => "success"

# Will raise MatchError if patterns don't match
# {:error, _} = {:ok, "success"}  # MatchError
