Top-level container for the current browser tab or window.
In a web browser, each window has a Window object, but within the context of a script, this object represents only the current window. Each other window, tab, and iframe has its own Window object.
Each window contains a Document object, which contains all of the window's content.
Use the top-level window
object to access the current window.
For example:
// Draw a scene when the window repaints.
drawScene(num delta) {...}
window.animationFrame.then(drawScene);.
// Write to the console.
window.console.log('Jinkies!');
window.console.error('Jeepers!');
Note: This class represents only the current window, while WindowBase is a representation of any window, including other tabs, windows, and frames.
