Typed.js

Typed.js is a simple library (more of a plugin, really) to animate typing on your screen. Once you enter any string, a visitor can watch it being typed at a set speed. Not only that, you can work the backspace button, as well as begin a new sentence. If you wish to allow visitors with JS disabled to also view it, you simply need to place an HTML div on the page. That way, bots and search engines also get to view the typed words.
