Getting new team members up to speed quickly can be a significant challenge. Standardizing a project's development environment using dev containers aims to make it easy for developers of all experience levels to contribute to the project, regardless of their local setup. This approach benefits teams by providing faster onboarding, consistency across environments, isolated dependencies, reproducible builds and tests, version-controlled environment, simplified collaboration, easier experimentation, and more. By implementing a standardized development environment using dev containers, teams can streamline their workflow, reduce issues related to environment setup, and allow developers to focus on building great software.
