Actors implements the Actor Model of concurrent computation. Actors

• interact via messages,
• represent computations and
• can create other actors.

Programmers can use actors to

• model computational concepts: e.g. atomic blocks, event handlers, state machines,
• implement concurrent objects such as servers, supervisors, firewalls and to
• compose them into an application.

Actors allows to write fault-tolerant Julia applications and make concurrency easier to understand.
