About the Author

Éric Bréhault wrote his very first web pages in 1993, started JavaScript application development in 1998, and is still enjoying it.

As an IT engineer, he has used a lot of different server-side technologies, but since 2006, he has been focusing on Plone—a Python open source CMS—and been an active participant of its community. His main contribution has probably been Plomino, a Plone-based application builder. He has also worked on different, modern web mapping solutions such as Leaflet.

JavaScript has always been an important part of his work, and he started using CasperJS in 2012 as his favorite testing utility. He developed Resurrectio, a CasperJS test recorder Chrome extension.

He works as a technical manager at Makina Corpus—a French open source consulting and development company providing services for web and mobile applications—specifically on environmental issues and in the fields of spatial analysis and data visualization.

I would like to thank all my teachers.
