What is npm and npx?

npm is like a big toy store where you can get tools and games for your computer [2][3]. npx is like a helper that lets you use those toys right away without having to keep them in your house forever [1][2].

Why do we need both?

npm keeps track of all the tools you want to use regularly and saves them on your computer [2]. npx is special because it can grab a tool, let you use it once, and then put it back without taking up space [4].

What's the difference?

When you use npm, you're saying "I want to keep this tool." When you use npx, you're saying "I just want to borrow this tool for a second" [2][3].

When do you use each one?

Use npm when you need a tool you'll use lots of times, and use npx when you just want to try something or run it once [1][4].
