While such techniques as threat analysis are increasingly recognized as essential to any serious development, there are also some basic practices which every developer can and should be doing as a matter of course. **A Guide to Proper Error Handling in JavaScript** [http://www.sitepoint.com/proper-error-handling-javascript/](http://www.sitepoint.com/proper-error-handling-javascript/)  In this article I would like to explore error handling in JavaScript. I will cover pitfalls and good practices.

This effort is being pushed by Google, and works on Android, but currently not backed by Apple – so no iOS support at the moment. **npm is the Beating Heart of the JavaScript Ecosystem** [https://hashnode.com/post/npm-is-the-beating-heart-of-the-javascript-ecosystem-cimvnbetj02r1wz53u4bjw1dr](https://hashnode.com/post/npm-is-the-beating-heart-of-the-javascript-ecosystem-cimvnbetj02r1wz53u4bjw1dr)  npm is the heart of the JavaScript ecosystem. It makes sure our modules end up where they’re supposed to. Pumping them out as needed. As JavaScript continues to grow, npm will grow with it. Supporting large enterprises, small startups, and tiny side projects. Being used for anything from web apps to robotics or home entertainment systems. **The current state of dependency inversion in JavaScript** [http://blog.wolksoftware.com/the-current-state-of-dependency-inversion-in-javascript](http://blog.wolksoftware.com/the-current-state-of-dependency-inversion-in-javascript)  [http://inversify.io/](http://inversify.io/)  Learn about the past, present and future of dependency inversion in JavaScript. Over the last year and a half, I’ve been reading a lot about dependency inversion and taking a look to the source code of many open-source IoC containers for JavaScript. At the same time I’ve been working on the development of InversifyJS (a powerful IoC container for JavaScript apps powered by TypeScript). **Docker - libcontainer Principles** [https://github.com/docker/libcontainer/blob/master/PRINCIPLES.md](https://github.com/docker/libcontainer/blob/master/PRINCIPLES.md)  In the design and development of libcontainer we try to follow these principles: - Don’t try to replace every tool. Instead, be an ingredient to improve them. - Less code is better. - Fewer components are better.
