What is WSL 2+Docker?

WSL 2+Docker is a powerful combination of two popular technologies: Windows Subsystem for Linux (WSL) 2 and Docker. WSL 2 is a compatibility layer for running Linux binary executables natively on Windows 10, while Docker is a containerization platform that allows users to package, ship, and run applications in containers. By combining these two technologies, developers and IT teams can create a seamless and efficient development environment for building, testing, and deploying applications.
