Elixir uses a 'let it crash' philosophy, encouraging developers to build resilient applications that can recover from errors using supervisors and error handling strategies.

Elixir adopts a unique approach to error handling, famously encapsulated in the 'let it crash' philosophy. This philosophy promotes the idea that rather than trying to prevent every possible error, applications should be designed to handle failures gracefully. To achieve this, Elixir leverages a process-based architecture where each process is isolated and can fail without affecting the entire system. When an error occurs, the process can crash and be restarted by a supervisor, which is a special kind of process designed to monitor other processes and manage their lifecycles. Supervisors use defined strategies such as :one_for_one, :rest_for_one, or :one_for_all to decide how to handle child process failures. This hierarchical structure allows applications to remain stable and responsive, as supervisors can restart processes that have encountered errors, returning them to a known good state. Additionally, Elixir provides mechanisms like try/catch for catching exceptions in specific contexts when needed, allowing developers to handle errors selectively. By embracing this model, Elixir developers can build robust applications that are resilient to failures, ensuring high availability and reliability.
