+# web-scroller
+
+A utility program written in JavaScript to scroll a web page with infinity scroll capability (social media). When you start the program, it begins scrolling the current page, and will continue scrolling as additional content is loaded. It does not stop until it hits the configured limit or the page has legitimately reached its end.
+
+## Running the Program
+
+Just copy the text of the [web-scroller.js](web-scroller.js) file into your browser's console and press ENTER. The script does not communicate with any network resources at all. It simply scrolls the current page with providions for the page to dynamically grow (infinity scroll, social media, blogs, etc.)
