If you make a copy of a string, number or boolean, the copy is not going to update when you change the original. However if you do the same with an array, this is just a reference so it will update the copy if you assign the array new variable.

To actually make a copy of an array - that wont then be modified by the changes made to the original - call slice against is which will return the whole array, i.e.:

const team2 = players.slice();

OR make a new array and concat the copied array into this one:

const team2 = [].concat(players);

Download node.js from https://nodejs.org/en/ (download recommended version). This should also download npm (node package manager).

The GUI did work but I had to close and re-open the command prompt in order to see that. 

Check that npm has been installed with npm -v. 

Nav to correct directory and go through npm init.

npm will have created a bunch of files - the package.json file will appear in the directory.
