If you do not have node, the recommended way to install it is with the following
$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
Download ZIP and unzip file, or clone repo from terminal. If you already have the folder locally, you may skip this step.
$ git clone https://github.com/taylulz/favorite_things_cli.git
From your terminal, navigate into to folder: $ cd favorite_things_cli
Run npm i to setup tests
Run tests with npm test. There should be 9 passing tests.

$ npm install --location=global
Run the program by typing the following into the terminal...
$ key-value
...and you will be met with the following command prompt
>
The put command can receive exactly two arguments, a key and a value separated by one space. Input more or less and expect to see Invalid syntax. in the terminal. If run sucessfully and stored in state, expect to see ok. If given an existing key, the put command will update that key's value.
> put favorite_color // 👈 only one argument
Invalid syntax.
> put favorite_color purple
ok
> put favorite_emoji 😋
ok
The fetch command can receive exactly one argument— a key. Input more or less and expect to see Invalid syntax.. If a value for that key exists, the value will be printed to the terminal. If a value for that key does not exist, expect to see Value not found. in the terminal.
> fetch favorite_color purple // 👈 more than one argument
Invalid syntax.
> fetch favorite_emoji
😋
>fetch favorite_animal
Value not found.
The exit command closes the session. You may also use ctrl+c. The session's state will be erased.
> exit
Bye!
If any unknown commands are received, expect to see the following string
Unknown command. Known commands are: put, fetch, exit
If you wish to uninstall the tool, run the following. Then delete the folder favorite_things_cli
$ npm uninstall --location=global favorite_things_cli
The tool must be able to be run from the command line by typing "key-value".
Running the tool must open an interactive session that accepts put, fetch, and exit commands. When ready to accept a command, it must output the string "> " as a command prompt.
put command should accept a key and a value, for example, "put favorite_color purple". If the key already exists, the old value should be replaced. If successful, the command should output the string "ok".
fetch command should just accept a key, for example, fetch favorite_color. If a value with that key has been entered, it should output that value ("purple"). If no value has been entered for that key, it should output the string "Value not found."
The exit command should output the string "Bye!" and exit the program.
If any other command is entered, it should output the string "Unknown command. Known commands are: put, fetch, exit".
If a command has the wrong number of arguments or is otherwise malformed, it should output the string "Invalid syntax."
your program should accept any reasonable strings as names and values.
$ key-value
> put favorite_color purple
ok
> put favorite_flavor strawberry
ok
> fetch favorite_color
purple
> fetch favorite_animal
value not found
> exit
