The Jet Programming Language

Jet, a general purpose programming language released in October 2026 and currently in alpha, compiles programs to native executable binaries using LLVM as its compiler backend, with a hand-written compiler front-end and IR layer. Jet supports both object-oriented and functional paradigms, uses syntax similar to TypeScript and Swift, provides dynamic arrays and strings, automatic memory management, and control over passing values by value or by reference. The language is licensed under Apache License, Version 2.0, with compilers distributed through its GitHub Release Page and documentation at jet-lang.com/docs.

Jet is a general purpose programming language that aims to strike a balance between ergonomics and performance. It was released in Oct 2026 and is currently in alpha. Quick Facts: - It supports both OOP and functional programming paradigms - The syntax is similar to Typescript and Swift - Arrays and strings are dynamic - Memory is automatically managed for you - You have full control over how values get passed around by value or by reference - Programs compile to native executable binaries - LLVM is used as the compiler's backend - The compiler front-end and IR layer are written by hand. - AI was strictly used for learning purposes and to help make sense of obscure LLVM errors. Here is a simple hello world program: // main.jet print "hello world" ; bash $ jet ./main.jet outputs ./main $ ./main hello world Please visit jet-lang.com https://jet-lang.com to learn more.
