The Premise

A common introduction to concurrency is the simple task of spawning two threads, then printing “ping” and “pong” in order N (N = 5 in the following examples) times.

This task is a light intoduction to synchronization primitives like mutexes and condition variables, or in more modern-concurrency models, channels / thread-safe queues.

I figured it’d be interesting to see what this task looks like in different programming languages, so I decided to code it in my four favorite programming languages (python, rust, golang, c++, in that order) to get a sense of their concurrency libraries.
