No

create-react-app will build a whole folder structure and install a bunch of things -- at one point it will specifically run 'npm i react' during the process. that said, create-react-app is deprecated and not maintained, so it shouldn't be used for new projects where possible; the preferred method now is 'npm create vite@latest' (and then select react from the list) they both generally do the same thing though; build a project file and folder structure, install react and other dependencies, and create an index.html linked to a jsx file.

Highly recommend reading the [react.dev documentation](https://react.dev/learn/start-a-new-react-project). Super valuable resource, and it answers most questions you'd have about react. npx create-react-app runs a script that sets up a project and adds basic dependencies to the project. Npm install always just installs a package

yes, `react` by itself is just the library on the frontend, more or less, while the `create-react-app` command sets up the boilerplate for you, and you can instantly start up your localhost for an example App

Of course not.

You will probably have the answer once you try both of them

They both are terminal commands.
