Why "this.tabs" is an array?


Why in this case, “this.tabs” is an array ?

var Window = function(tabs) {
  this.tabs = tabs; // We keep a record of the array inside the object

I would have written:

var Window = function(tabs) {
  this.tabs = [];

if it’s an empty array you can’t have a reference to the array passed in to the function
it’s an array because the function parameter is an array

look at when Windows is used: it has an array as argument

// Let's create three browser windows
var workWindow = new Window(['GMail', 'Inbox', 'Work mail', 'Docs', 'freeCodeCamp']); // Your mailbox, drive, and other work sites
var socialWindow = new Window(['FB', 'Gitter', 'Reddit', 'Twitter', 'Medium']); // Social sites
var videoWindow = new Window(['Netflix', 'YouTube', 'Vimeo', 'Vine']); // Entertainment sites
