Composer is one of the most influential tools to have come out of the PHP ecosystem. Not only did it help revolutionize the PHP package ecosystem by making it easy to autoload code, find packages, and keep track of dependencies, it also stands as one of the best package managers from any language, hands-down. Python’s pip, NuGet for .NET, Rust’s cargo, and Go’s dep all pale in comparison to the stability and simple usage of Composer.
