How do i check what version of react i am using?

Have you ever been curious to know which version of React you are using? If so, you're not alone. React is one of the most popular open-source JavaScript libraries for creating user interfaces, and its latest version comes packed with exciting new features. But how can you check which version you're running? Read on to find out!

Step One: Open Your Command-Line Interface (CLI)

The first step to checking which version of React you are running is to open your preferred command-line interface (CLI). If you're not familiar with what a CLI is, it is an application that allows you to manage your computing environment from the command line. For macOS, the default CLI is called Terminal, while for Windows users, the default option is Powershell. Once opened, type into whatever CLI interface program your using: `npm -v GET`. This command will return a number representing the version of npm (the Node Package Manager) installed on your system. If npm isn't installed on your system, then the command will fail and prompt you to install npm if necessary.

Step Two: Check Your Package Dependencies

Once you have determined what version of npm (Node Package Manager) you are running, it's time to check your package dependencies. To do this, navigate to the root directory of your project in the CLI window and type in `npm list --depth 0`. This will return a list of all the package dependencies that are running in your project environment. Among those listed should be an entry for `react@X`, where X represents a number representing the version of React installed in your project environment. For example: "react@16.8" would indicate react version 16.8 is currently being used in your project environment.

Step Three: Confirm It Is Installed In The Correct Environment

To ensure that this version of React is indeed being used in your project environment, navigate back one directory level by typing 'cd ..' and run another dependency check by again entering `npm list --depth 0`. This will also show if there are duplicate dependencies at different versions within the same root directory level—a situation that can lead to conflicts when trying to use certain apps or modules within Node modules. If no duplicate dependencies weren't found—as indicated by only one listing for a given module—then that listing should match the original 'react@X' entry determined by running 'npm list --depth 0` earlier on in returning this same exact result again should indicate that it has successfully been installed within that correct environment/location and at its current indicated version as part of all package dependencies at this depth level/location.]
