Eslang

Eslang is a functional programming language designed for building distributed and fault-tolerant systems. It draws inspiration from Erlang, a language known for its robustness and scalability, particularly in telecommunications and concurrent applications. Eslang aims to provide a similar set of features while potentially offering a different developer experience or targeting specific niches.

The core of Eslang's design revolves around lightweight processes, which are isolated units of execution that communicate with each other by sending and receiving messages. This message-passing concurrency model is fundamental to building resilient systems, as the failure of one process does not necessarily bring down the entire application. Eslang emphasizes immutability, meaning data cannot be changed after creation. This property simplifies reasoning about concurrent programs and helps prevent common bugs.

Eslang's syntax and semantics are designed to be clear and expressive, facilitating the development of complex distributed applications. Error handling in Eslang often involves supervisors, which are special processes responsible for monitoring other processes and restarting them if they fail. This hierarchical supervision strategy is a key component of Erlang-family languages' fault-tolerance capabilities. While specific implementations and adoption levels may vary, Eslang represents an effort to extend the principles of concurrent, distributed, and fault-tolerant programming to new contexts or with alternative approaches.
