It says https://www.npmjs.com/package/ijavascript

In Windows, Anaconda offers a convenient distribution to install Python and many other packages, such as Jupyter and IJavascript.

But it isn't explained how. Neither on Anaconda site (once Anaconda is already installed).

Update: I know about 

npm install -g ijavascript
ijsinstall

But then what's difference with Linux ? Because I got this error, I thought there was something specific on Windows.

Error running jupyter --version Error: Command failed: jupyter --version 'jupyter' is not recognized as an internal or external command, operable program or batch file.

It should probably say "such as Jupyter, where IJavascript can run", but just like the documentation says

  1. Anaconda installs Jupyter for you
  2. You need Nodejs and NPM for ijavascript to work

Then

npm install -g ijavascript

Followed by 

ijsinstall

You need to run jupyter from the Anaconda prompt, or add Anaconda's executable binaries to your PATH (which is an option during installation). As that error is directly from CMD, it has really nothing to do with Anaconda, Jupyter, or ijavascript directly, but rather you are missing some OS setup

  • See update: I forgot to mention I already tried that, it didn't work, I got an error: Error running jupyter --version Error: Command failed: jupyter --version 'jupyter' is not recognized as an internal or external command, operable program or batch file. – user310291 Feb 10 '18 at 10:31
  • You should either learn about what the `PATH` variable on your OS means and how to change it, or search that error and read https://stackoverflow.com/questions/35134225/jupyter-from-cmd-line-in-windows – OneCricketeer Feb 10 '18 at 13:06
  • I never said to run the jupyter command anyway, so I'm confused why you're doing so... Your question made me think that you already were able to run Jupyter and you just wanted Javascript support in it – OneCricketeer Feb 10 '18 at 13:08
  • I added C:\ProgramData\Anaconda3 to path and I still get the same error. – user310291 Feb 10 '18 at 17:51
  • Look in that folder. Do you see a file named jupyter? – OneCricketeer Feb 10 '18 at 17:54
  • There's a lot of files and folders but I can't see jupyter, I can see python.exe and Uninstall-Anaconda3.exe – user310291 Feb 10 '18 at 19:32
  • 1) The Anaconda installer already asks if you want it added to the PATH, and you should check the box. 2) The **Anaconda Prompt** is where you can enter the jupyter command, if you see the question I linked above, otherwise, I trust your ability to search elsewhere for how to add jupyter to your Windows CMD PATH, as this question was originally for ijavascript – OneCricketeer Feb 11 '18 at 00:22

Run ‘pip3 install jupyter‘ in the command shell.

Look through this site to get some help. Google and YouTube will be very good friends to get this set up.
