The way a website works is you are making a choice to open a page. This choice is made based on what your device is equipped with, or what a browser supports, or what the user’s experience of the site is. For example, if you’re on a cell phone, your browser will make an attempt to open a page. If you’re on a tablet, your browser will make an attempt to clear the input field so the site can render.
With this method, you can send a request to send a clear input and send the string of text that you want the browser to clear. This is very useful for clearing text input or making sure text is cleared after a function returns.
A nice thing about this method is that it uses a callback function which gets called when the browser is not running, but it is still very handy when you are running on a real-time computer.
