1. Package Execution npx (npm execute): npx is a tool that executes Node.js packages. If the package is installed locally or globally, npx will use that version. If the package is not installed, npx will download a temporary copy, execute it, and then remove it. This is particularly useful for running packages that you don't need to install globally. 2. Pros npx (npm execute): Avoids global installation, reducing the risk of version conflicts. Allows you to easily run packages without permanently installing them. Great for trying out new tools or running one-off commands. Makes it very easy to run specific versions of command line tools. 3. Cons npx (npm execute): Requires an internet connection to download packages that are not already installed. Can be slightly slower than running globally installed tools.
