Node.js / JavaScript - JavaScript window variable breaking functionality

So on my Jade template, I am passing it a variable through the route which contains an array of names.

Here is the JavaScript from that template:

script(type='text/javascript')
  window.teams = !{JSON.stringify(teams)};

teams contains the array I spoke about. Here is the JavaScript:

$(function () {
  // Array of team names
  var teamNames = [];
  for(var i = 0; i < teams.length; i++) {
    teamNames.push(teams[i].name);
  }

  var bracketTeams = [];

  var teamMatches = new Array();
  for(var i=0;i<teamNames.length; i+=2)
  {       
    teamMatches.push([teamNames[i],teamNames[i+1]]);
  }

  var bracketData = {
    teams : teamMatches,
    results : [[
        [ [1, 0], [1, 0] ],
        [ [1, 0], [1, 0] ]
      ]]
  }
    $('#tournamentBrackets').bracket({
        init: bracketData
    });
});

Now for some reason, the functionality of the rest of the system completely breaks when I add in this JavaScript code. If I comment it out, then the rest of the system works fine, if I leave it in, buttons do nothing, links go nowhere, data isn't added (although the data is loaded, i.e a database of teams is listed). If I load the page, then uncomment the JS, the page works as it should though.

Any ideas what is breaking my system in this code? I just tried renaming window.teams to window.testName and it still broke. Really confused.

In Node.js, the window object probably does not exist. Node.js has a different global object than browsers do. In Node.js, the global object is actually named global. Unless you have specifically set up an object named window, you're probably getting a ReferenceError when you try to assign values to window.teams
