C++ vs. CoffeeScript vs. JRuby

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;

C++ is used in Shiro (https://github.com/Marc3842h/shiro).

C++ is a high performance, low level programming language. Game servers need to run with fast performance to be able to reliably serve players across the globe.

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.
