Justin Scherer has been professionally developing JavaScript applications for over 10 years. On top of this, he has worked in a variety of fields, ranging from embedded systems to high-performance cluster applications. Utilizing JavaScript to cluster simulation models, write RFID tracking systems, and even to hook Fortran code together, Justin brought JavaScript to Argonne National Laboratory as a way of quickly prototyping and building out ideas.

Justin then went on to work for an e-learning start-up and lead the frontend development team. He currently works for a large financial institution, where he is leading the charge on developing a highly performant frontend and middleware through the use of JavaScript.

During his time off, he has a handful of hobbies, including but not limited to playing the piano, going to concerts, repairing watches, reading, and spending time with his wife. He enjoys his time with his wife and their cat and dog. His mind is constantly wandering to new areas where technology, especially web technology, could prove useful.

Jean-SbastienGoupil is a web developer with more than 15 years of experience. He previously worked for Microsoft and is now a web architect consultant for his own company, working with new clients on web products. He champions quality and consistency at every opportunity and is driven to help others through teaching and blogging.

In his free time, he codes barcode software. He loves sports, hiking, canoeing, crabbing, and chatting about technology.

Much of today's web environment has changed dramatically not only in terms of creating web applications but also when it comes to creating server-side applications. A frontend ecosystem that was dominated by jQuery and CSS frameworks such as Bootstrap has been replaced with reactive, fully fledged applications that could be mistaken for an application running on the desktop.

The language we write these applications in has also changed in a dramatic fashion. What was once a mess of var and scope issues has turned into a fast and easy-to-program language. JavaScript has not only changed the way we write our frontend, it has also changed the backend programming experience.

We are now able to write server-side applications in the language that we write our frontend in. JavaScript has also modernized, and possibly even popularized, the event-driven system with Node.js. We can now write code for both our frontend and backend in JavaScript and possibly even share the JavaScript files we generate between the two.
