   PEB users can enter a lot of data in local HTML forms and it is often important to safeguard this information from accidental deletion if PEB window is closed without first saving the user data. When user starts closing a PEB window, the browser checks for any unsaved data in all forms of the HTML page that is going to be closed. This is achieved using internal JavaScript code compiled in the resources of the browser binary.  
 
   If any unsaved data is detected, PEB tries to determine what kind of JavaScript routine has to be displayed to warn the user and ask for final confirmation. Two types of JavaScript warning routines are possible in this scenario: synchronous and asynchronous.  
@@ -239,7 +239,7 @@ They have two functions:
 
   The asynchronous warning function does not rely on JavaScript Confirm dialog, does not stop the execution of any JavaScript code within the page and does not wait for the user's decision. If the user chooses to close the window, a special window-closing URL, ```http://local-pseudodomain/close-window.function```, has to be sent to the browser. Upon receiving this URL, PEB closes the window from where the window-closing URL was requested. The warning dialog can be styled to blend with the rest of the HTML interface or to attract attention and this is the main advantage of using an asynchronous warning dialog. Developers can implement it using any suitable JavaScript library or custom code.  
 
-  The following code is an example of both synchronous and asynchronous warning functions. It is expected, that one of them will be present in a PEB-based application where user data is to be protected against accidental loss. If both functions are present, the asynchronous one will take precedence. The asynchronous function in the example code is implemented using [jQuery](https://jquery.com/) and [Alertify.js](http://alertifyjs.com/).
