Let Vim do the typing, and Integrating js-beautify into Vim

Details
In April's meetup, George Brocklehurst (@georgebrock) will show Vim's various built-in completion mechanisms. This will let us let Vim do the typing, writing fewer typos and faster.
Also, Noah Frederick will do some "pair programming" with all of us with two VimScript tasks:
• An enhanced version of the built-in :marks command called :Marks, that allows us to jump immediately to a mark in the list with a single key press
• js-beautify (https://github.com/beautify-web/js-beautify) is a command-line formatter for JavaScript, JSON, and CSS files. Create a :JsBeautify command that seamlessly integrates the js-beautify utility with Vim.
If you'd like to present as well, please get in touch! We are always looking for speakers who have got something cool to share about Vim.
See you all on April the 9th!
