Beef is an open source performance-oriented compiled programming language which has been built hand-in-hand with its IDE environment.

D (Programming Language) is described as 'D is a language with C-like syntax and static typing. It pragmatically combines efficiency, control, and modeling power, with safety and programmer productivity' and is a popular programming language in the development category. There are more than 50 alternatives to D (Programming Language) for a variety of platforms, including Linux, Windows, Mac, BSD and Self-Hosted apps. The best D (Programming Language) alternative is Python, which is both free and Open Source. Other great apps like D (Programming Language) are Java, Rust, C++ and C (programming language).

Mussel is an interpreted programming language written in Rust. It was designed as a simple and flexible language with a focus on easy-to-read syntax and powerful expression evaluation. Mussel supports basic data types, variable bindings, functions, closures, control flow...
Pony is an open-source, object-oriented, actor-model, capabilities-secure, high-performance programming language.
The X10 programming language is organized around four basic principles of asynchrony, locality, atomicity, and order that are developed on a type-safe, class-based, object-oriented foundation. This foundation is robust enough to support fine-grained concurrency, Cilk-style...

HolyC is very similar to regular C, so it's a very simple but powerful language. It was used to make all of TempleOS, so it definitely works to make programs.

Vala is a new programming language that aims to bring modern programming language features to GNOME developers without imposing any additional runtime requirements and without using a different ABI compared to applications and libraries written in C.
FreeBASIC is a completely free, open-source, 32-bit BASIC compiler, with syntax similar to MS-QuickBASIC, that adds new features such as pointers, unsigned data types, inline assembly, object orientation, and many others.

Pike is a dynamic programming language with a syntax similar to Java and C. It is simple to learn, does not require long compilation passes and has powerful built-in data types allowing simple and really fast data manipulation.
