The article introduces Gleam, a functional programming language that targets the BEAM (Erlang VM) and can also be compiled into JavaScript. As a Rust developer, one may feel at home with Gleam due to its similar syntax and type-safe nature, with the author noting that about 80% of their Gleam code could be easily adapted to Rust. Gleam is designed for building scalable systems and boasts interoperability with the wider BEAM ecosystem, including Erlang and Elixir, making it an attractive option for developers looking for a friendly and efficient language.
