What is the difference between window, screen, and document in Javascript?

Reference

• Window is the main JS object root, and can also be treated as the root of the DOM.
• window.screen or just screen is a small information object about physical screen dimensions. The physical display’s full screen.
• window.document or document is the main object of the visible document object/model/DOM.
• Each browser tab has its own top-level window object, and each iframe has its own window too, nested within a parent window. window.window always refers to window, but window.parent and window.top might refer to enclosing windows. window also has:
  • setTimeout and setInterval, binding event handlers to a timer.
  • location giving the current URL.
  • history with back() and forward().
  • navigator describing the browser software
• document: Each window has a document object to be rendered. Then you can access stuff with document.body.something.
• The document is your document that gets loaded into the browser.
