Erlang Tutorials

Erlang: Building Concurrent, Fault-Tolerant Systems

Learn Erlang programming: history, BEAM VM, processes, message passing, OTP, supervisors, the let-it-crash philosophy, and building fault-tolerant systems. Step-by-step with examples.

Erlang Data Types — Numbers, Atoms, Tuples, Lists, Maps, and Binaries

Learn Erlang's data types: integers with arbitrary precision, atoms as named constants, tuples for fixed collections, lists, maps, and binaries for binary data.

Erlang Pattern Matching — The = Operator, Guards, and Function Clauses

Master Erlang's pattern matching: the match operator, variable rebinding, guards for validation, and multi-clause function definitions.

Erlang Functions and Modules — Defining, Exporting, and Organizing Code

Learn Erlang function definitions, module structure, public/private exports, attribute annotations, and code organization patterns.

Erlang Lists and Recursion — Tail Recursion and List Processing

Master list processing in Erlang: recursive patterns, tail-call optimization, list comprehensions, and the lists module.

Erlang Concurrency — Spawn, Send, Receive, and Process Linking

Learn Erlang's concurrency model: spawning processes, message passing, selective receive, process linking for fault tolerance, and monitoring.

Erlang OTP — gen_server Behaviours

Learn gen_server: OTP behaviour for stateful servers, call/cast/info message patterns, and start/init/terminate lifecycle.

Erlang Error Handling — try/catch, Exceptions, and 'Let It Crash'

Learn Erlang's error handling philosophy: try/catch for exceptional cases, the 'let it crash' pattern, and supervision for recovery.

Erlang Records and ETS — Named Fields and In-Memory Tables

Learn Erlang records for structured data and ETS tables for fast in-memory storage and retrieval across processes.
