Hello guys, I have been asking my readers to learn Docker since last year. Why have I been doing this? Because Docker is not just another tool, it's a game-changer, and I firmly believe that every Programmer, be it a Java developer, a C++ developer, or a Web Developer coding in JavaScript, all should learn Docker. The first and foremost reason is that Docker simplifies both the development and Deployment of Software projects, for example, you can deploy a Java Microservice in the same way as a node application once you wrap them in a container. Just like Maven made it easy to maintain project dependencies, Docker takes it to another level by building applications and shipping them into containers.

The Programming language you will use already has tried and tested implementation for those algorithms and that's what you will learn in this article.
