Elixir Pattern Matching

Pattern matching is a central Elixir skill. It is used for assignment, function selection, branching, and data extraction.

Destructuring

{name, age} = {"Ada", 32}

Guards

Guards let you refine a match with extra conditions while keeping the code explicit and readable.

Case flow

Use case expressions to handle several match branches without nested conditionals.

Practice

  1. Write one destructuring assignment.
  2. Use one guard in a function head or case branch.
  3. Write one note about how matching differs from assignment in imperative languages.
