I just started the challenge “Manage Packages with npm” and to my surprise, I could not understand an inch of it. Is it very difficult or is it just me who is facing problems. Although I am able to run the instructions mentioned but not able to understand the underlying concept!
I am not really able to make out what npm really is and what it does. Please help.
NPM is a package manager that enables you to use packages (software) written by others that your application might need. This is what the term ‘dependencies’ refers to.
It’s normal for a project to have many dependencies, so rather than manage each of these individually a package manager allows easier management (installing / updating / removing).
You might also have seen the reference to a ‘package.json’ file. This documents each package and which version your project depends on, this makes it easy for others to mirror your project by setting up from the package.json.
