Note: In reality, at this time browser requirements for access to the clipboard vary significantly. Please see the section Clipboard availability for details.
All of the Clipboard API methods operate asynchronously; they return a
Promise which is resolved once the clipboard access has been completed. The promise is rejected if clipboard access is denied.
Clipboard is based on the
EventTarget interface, and includes its methods.

The asynchronous clipboard API is a relatively recent addition, and the process of implementing it in browsers is not yet complete. Due to both potential security concerns and technical complexities, the process of integrating this API is happening gradually in most browsers. See the browser compatibility section below for more information.
In browser extensions, you can access the system clipboard using the WebExtension
