C++ vs. CoffeeScript vs. Erlang

Core linear algebra and optimization functionality for deep analytics and machine learning

The most latency sensitive parts are written in C++. Due to our interconnected services architecture, we use either Python or C++ for each service, with the performance critical parts being C++14.

Our online judge, 'Evaluator', is written in it.

legacy part

The Game Pencil Engine Editor is coded in C/C++.

Used in backend and clients for performance heavy tasks.

Performance, zero-overhead abstractions and memory safety of the modern C++ language make this the perfect language for the project.

High performance

The main programming language of ApertusVR. C++11 & CMake provides multi-platform targeting. The architecture is modular.

Used to write PHP extensions - AZTEC Decoder - License Driver scan - Axis2/C to PHP wrapper and Job-scheduler - Barbershop

std::cout << "Hello World!" << std::endl;

Javascript is a hell. We use coffeescript for its readability.

All front-end / back-end is driven by Coffeescript. For the main ReactJS functionality JSX is embedded with coffee in .cjsx files / handled by Browserify.

I use a lot to coding JS.

All our code is CoffeeScript, blending seemlessly in our JS stack

This is my language-of-choice for coding.

All frontend code written in coffeescript

See NodeJS once again.

CoffeeScript is good to write some utilities at front-end.

All of our Javascript code is first written in CoffeeScript for ease of reading / writing. It is compiled to Javascript before being minified and served to the client.

We like CoffeeScript because it's more readable, we use it because we have a lot of libraries and functions already (plays nicely with Rails, too)

We prefer typescript.

Very nice programming language, used for backend integration.

The central business logic and ETL engine is written in Erlang.
