This page alerts a function and a variable directly on the window object, to demonstrate that the global context is the window object.
Here is the code:
var sport = "baseball"; var player = null; function getPlayer() { if (sport === "baseball") { player = "Evan Longoria"; } else { player = "Eva Longoria"; } var player2 = "Derek Jeter"; return player; } alert(window.getPlayer()); alert(window.player);
