Ground Control to Major Tom: How NASA Uses Node.js
Image from Pixabay.During a spacewalk in 2013, Italian astronaut Luca Parmitano found himself in grave danger â€” water was leaking into his helmet. The water quickly migrated in zero-G to his eyes, ears and nose. Quickly, Luca was struggling to hear and see and he began having trouble breathing. Fortunately, his partner for the spacewalk, Chris Cassidy, was nearby and guided Luca into the airlock a

Babel-free backend prototype - challenge accepted â€” Xebia Blog
This post is part of a series of ES2015 posts. Weâ€™ll be covering new JavaScript functionality every week! In several previous posts weâ€™ve been using Babel to actually run our (transpiled) code.
