Experience

Underscore Templating for Atom

https://github.com/dborstelmann/atom-underscore

I realized there was no syntax highlighter for Underscore templates in Atom, so I decided to build one! I developed it using Atom's easy extensibility process. Now developers using Underscore's templating system can more efficiently develop HTML files with data.
