Incase you haven't heard the news, JavaScript and NodeJS are single handedly eating the world of software. NodeJS is an Open Source server-side JavaScript environment based on the V8 JS engine found in Google Chrome. Once only thought of as "hipster" technology, NodeJS is quickly becoming one of the most commonly used environments for building web applications and is beginning to find its way into the Enterprise.
Below is a list of 5 huge companies who have adopted the popular "hipster" server-side JavaScript engine for use inside high traffic, high profile production projects.
#1 NETFLIX
Nexflix used JavaScript and NodeJS to transform their website into a single page application. Traditionally, Netflix has been an enterprise Java shop, but “as we migrated out of the data center to the cloud we moved to a more service-based architecture,” Trott said. The company is in the process of breaking up what used to be a monolithic Java application into a set of smaller services. Java still powers the backend of Netflix, but all the stuff that the user sees comes from Node. In addition to Node, Netflix is also using ReactJS in their stack.
#2 PAYPAL
PayPal too is moving away from Java and onto JavaScript and NodeJS for use in their web application platform. PayPal began using NodeJS as a prototyping platform and when it proved extremely proficient and they decided try it out in production. Â PayPal's first usage of NodeJS in production wasn’t a minor application; it was their account overview page which is one of the apps most trafficked features. As insurance, the PayPal team simultaneously developed the same "account overview" rebuild using Java and the results proved their hypothesis proved that the JavaScript team was able to build the product both faster and more efficiently. Since this transformation PayPal has since released an Open Source extension for ExpressJS called KrakenJS which can add an extra layer of security and scalability to your NodeJS Server.
#3 UBER
Uber has built its massive driver / rider matching system on Node.js Distributed Web Architecture. Check out the keynote from Uber's Tom Crouche at the Node.js Interactive Conference below. Tom is a senior site reliability engineer and talks about how Node.js is being used at Uber and how future growth requires the community to push the boundaries and expectations for Node.js. Uber’s GitHub page is a good source to also learn more about the company’s most critical systems.
#4 IBM
IBM has also embraced NodeJS as well. Myles Borins from IBM spoke about his experiences during this past NodeJS Interactive conference. Here is what he had to say: "During October of 2015 I was given the task of working on The Canary in the Gold Mine, a smoke testing utility that automates running unit tests of various various modules in the node.js ecosystem. CITGM has been incredibly successful, finding all sorts of regressions across the ecosystem and in node core itself.
#5 MICROSOFT
Even Microsoft has embraced NodeJS, offering direct integrations into their Azure Platform, releasing a wealth of tutorials targeted at Node and they have even announced plans to fork the project and build their own version of Node powered by their Edge Javascript engine instead of Chrome's V8.

Atwood's Law (10 years old already 😮)
"Any application that can be written in JavaScript, will eventually be written in JavaScript."
I'm old enough to remember the time when it was "Any application that can be written in BASIC will be written in BASIC".
I am old enough to have used MS BASIC 1.0. Nobody was saying that. They were saying PASCAL would be the language to follow as I remember. They werent even teaching C in most universities. Things have moved on somewhat from 1981. The kids are being taught Node as undergrads, it's really impressive.
History has not ended. We are neck deep in frameworks and all sorts, there plenty to argue the toss about. But the Perl->Python->PHP->JavaScript odyssey is over IMO. We are going to have all kinds of MochaBerryHotRoastScript and God knows what else, but they are all going to be ECMAScript compatible.
Lester's Proposition: If you are stood in a green field and your competitor is in the next field using JavaScript. If you dont follow suit they will rape you.
never hear of this Atwood's law. :) thanks
Serious question: why do people like JavaScript so much? I thought people found it horrible. Also, because JS isn't type safe, does this mean it's prone to bugs and crashes because of this?
Here is an article I read some time ago by Eric Elliott about static types. Static types doesn't seem to have enough impact on bug density based on his analysis.
I can't speak for anyone when it comes to Javascript love, but there is a quote from Bjarne Stroustrup ( creator of C++ ) that I like:
I imagine all programming languages are horrible, if they were not, we would stop coming up with new ones.
Not all programming languages are applicable to all problems. Also tech changes. A lot.
complain != horrible. Javascript is horrible to work with. I complain about python all the time.
Those are diff statements.
A few reasons. It's syntax is easy to learn, and it opens the door to both client and server side development. You have to know it to do anything on client side, once you learn that much why not learn Node.js?
It's drawbacks are well documented in "Javascript, the good parts". Typescript will help improve it, but it will never help prevent programmer mistakes anywhere near as well as Swift (for example). But no language is perfect.
Is has been my experience that as your software gets larger and more complex, the lack of type safety causes more and more problems. That's why we use Typescript to compensate for the lack of type safety in JavaScript. I think that is one of the reasons JavaScript is becoming so popular. It doesn't matter what you develop in if the ecosystem allows everything to be compiled into JavaScript. Javascript and V8 are similar to the Microsoft CLR and Java JVM -- a universal run time.
Except that JVM and CLR are specifications, V8 is an implementation of no specification. There are multiple Java byte code interpreters, multiple JVMs. There is just one V8, and a hack build on top of it called NodeJS. NodeJS doesn't run on any other JavaScript runtime except V8.
NodeJS is like JavaScript as Microsoft VisualJ is like Java.
Maybe this was true back in 2017, but now there's a NodeJS build for the ChakraCore runtime as well.
Yes. And this is where Elm fits into the ecosystem really nicely.
People don't really love it. It just happens to be the only language the browsers speak and they had to learn it. Then it expanded to other systems and things became more interesting. Even with all the improvements, JavaScript still feels hacky.
"People don't really love it"
False, it's my favorite language.
And it's the only programming language that you know well, isn't it? =)
Bingo.
Now we have ES6 version of javascript that has classes etc., I haven't explored much, but I have seen it makes you write code in different way like other mature programming languages
Yes, but we can ignore the obvious flaws and use things like TypeScript to transpile our code rather than admitting there are better tools.
I don't particularly like JavaScript and wouldn't choose Node by default, but it's not a strict dichotomy. Circumstance is everything and there are a lot of circumstances where JavaScript really is the right choice, mostly because it's ubiquitous and models can be expressed the same across all environments. We got to this point not because of JS's greatness, but because of pragmatism. That can't be ignored.
I think the reason JS gets so much attention is because it is probably the easiest language to get into, and a language web developers already (are required to) speak. Nearly every computer has a JavaScript runner and debugger built in -- the browser. Pick one of the many good syntax-highlighting editors and you are off to the races. Then it's a natural progression to exploit the required JS proficiency and use Node for the back-end.
This does not make JS a good language to actually use. But regardless it will continue to flourish as long as it maintains its monopoly as the only language browsers understand. And Node's fate is tied to JS.
For me the trade-offs are just not favorable for using node in back-end systems. Nor JS anywhere I don't have to.
JavaScript has grown beyond recognition in the last 10 years. The main reason to use it is because it is everywhere already: it's in your browser, in your PDF viewer, even your old flash plugin, the server and even embedded in microcontrollers.
It may not be the most beautiful or effective language, but it gets the job done. Miss strict types? Use either TypeScript or Flow. Tired of waiting for new language standards to become usable? Babel your way out of that. You don't like to write JS at all? Compile your Java or C(++) Code to JS using GWT or emscripten.
Not performant enough? Since Google broke into the market with V8, JS performance gains are found left, right and center - not only for your product, but for every product using JavaScript that runs V8 - and other engines will follow or even outperform V8.
"write once, run anywhere"
just not the language Sun hoped for :-D
I am happy to hear of JavaScript adoption in any enterprise business. Soon we will JS all the things!
Yeahh! all points towards that, Js is all over the place which is awesome, even hardware.
Great article it's always cool to read about what big companies were/are using and what they're up to.
Personally I think that JavaScript is the next Java
The way that the JS ecosystem is exploding right now totally reminds me of Java in the early 2000's. And what's not to love about it (OK there is a couple things)
But with ES6 and classes + TypeScript it's starting to head towards a more traditional route (optionally)
And Node.JS makes everything better
It is apparent that there is a lot of bias towards JQuery, and perhaps JavaScript as well. It would have been informative if this article had referenced the number of Fortune 1000 sites that use JQuery as compared to Node.js. To reference only a "few" doesn't tell the entire story....
Agreed. jQuery is defanitly a needed skill to know if you are going to be doing web dev. If we tried to list all the websites using jQuery I think we would run out of room on the list. "According to recent research by W3Techs, jQuery is now used on half of all websites worldwide. The popular JavaScript library has come a long way since John Resig’s Selectors in Javascript blog post in 2005." We actually met John Resig, founder of jQuery, at a meet up and he admitted to not using jQuery in years and only using React on a daily basis for what ever that is worth.
Interesting that the JQuery creator moved on eh? Of course, the history of software has always been about the "next great thing" hasn't it? Anybody remember APL now?
I enjoyed your article, and responded only because I am still a big fan of JQuery.
I enjoy using JQuery as well. I am pretty sure every single programing language out there gets a bad wrap by someone else. Don't listen to the trolls .... do what makes you happy and gets the job done!
The reason for using jquery on sites is very simple "All css frameworks don't have libs for every js framework or lib but jquery", so to me, it doesn't make sense to have jQuery in an angular app just because i want a modal from bootstrap and other beauties from angular. In that case I would rather stick to using jQuery and jQuery alone.
I'd say that being able to spell would be the primary skill for any job. "My rabbit has one ear and he's def in it"
Minor correction, Microsoft did fork Node.js to run on Chakra and contributed it back, the release is called Node-ChakraCore and can be downloaded from GitHub or Node.js's website. But it's not a fork like
io.jswas, it's a fork to enable a different runtime and address how to handle C++ node modules via NAPI.JavaScript FTW!!! 🙌
