The Power of Erlang: A Functional Fault Tolerant Programming Language

🚀Erlang is a functional fault-tolerant programming language known for scaling up the telecommunications industry.

🔄Erlang provides fault tolerance by letting failed processes crash without affecting the entire system.

📦Erlang's process isolation enables hot code swapping at runtime for software updates with zero downtime.

🌐The Erlang ecosystem, including the BEAM virtual machine, is open source and still used today.

💬Erlang's message passing model facilitates highly concurrent systems, handling billions of messages daily.

What is Erlang known for?

00:00Erlang is a functional fault-tolerant programming language known for scaling up the telecommunications industry.

01:09To get started with Erlang, declare a module and write a function containing one or more expressions.

01:31Erlang's concurrency model allows for executing functions concurrently using the spawn primitive.

01:51Erlang's message passing model enables communication between processes using the send operator and the self ID.

02:27Erlang's receive block allows a process to suspend execution until a message is received.

02:39The Erlang ecosystem, including the BEAM virtual machine, is still in use and actively developed.
