Minimize browser window using Javascript

There is no way to minimize the browser window within javascript.

There are ways to change the size of the window, but no true minimization (nice word)

If you use an extension, then you can minimize by chrome.windows.update(window.id, { state: 'minimized' })

No, there isn't. However, depending on what you're doing and which browsers you're targeting, you could play around with the blur and focus events of the window to achieve similar effect.
