Javascript started as a simple, and admittedly poorly designed scripting language made for doing cute little things on a browser in 1995. Over the time, it spread out in a dominant way for interacting with each of the various web browsers and with the invention of node.js in 2009, the floodgates opened.

Today, almost 98% of Walmart’s traffic is served via node API and NASA (yes, the same NASA which publishes pictures of various galaxies and sends people to moon) has accepted node enterprise architecture for mission critical systems.

Why JavaScript matters

• Microservice architecture has taken the software market by storm with its ability to scale only part of the application, allowing large teams to work in parallel. While other languages are quite capable of creating microservice, only few can offer a combination of development speed, memory usage and scalability of Node.js.
• All frontend web development are already happening in JavaScript based frameworks. With the invention of Nodejs as your backend engine, it provides a lot of productivity benefits. Suddenly, the libraries can be reused, tools can be standardized for both front-end and backend.
• Javascript is constantly improving. With the ES6 spec for JavaScript, and continuous and fantastic releases of Node foundation, it will continue to get better with time.
• iphone and Android applications : react native, a JavaScript library now provides native-quality experiences for significant portions of Facebook’s mobile applications in addition to those of companies like CBS Sports, Vogue, and apparently Walmart in the near future.

In its several years in existence, JavaScript has made a significant impact on a number of small and large companies — and it’s only getting started. With ever increasing investment, it is expected that JavaScript will continue to mature and expand its enterprise capabilities.
