So why would I want to learn Node.js?

It is the future of web development.
Node.js is a representative of a younger web development generation.

So what is Node.js?

Before I looked into Node, I was confused as to what this open source development platform was. I was used to the old PHP scripting language that powers most of the popular Content Mangement Systems (CMS) today.

I discovered that Node.js is not a language such as PHP:

  • Is a JavaScript runtime environment built on Chrome’s V8 JavaScript engine.
  • Is asynchronous programming which ensures the non-blocking code execution (executes without having any dependency and no order).
  • It operates on a single threaded event based loop.
  • It’s an ecosystem package (npm) – and is the largest ecosystem of open source libraries in the world (it surpassed Ruby on Rails).

So Why Learn Node.js?

1) It is the future of web development
A new generation, Node.js is a representative of a younger web development generation.

2) Gained popularity
According to a 2017 Stack Overflow survey, Node.js was the most popular platform under Frameworks, Libraries, and Other Technologies.
On a side note, JavaScript was the most popular programming language.
Can you see the relationship?
As web technology heads in this direction, it appears that developers will eventually need to learn Node.js to stay relevant in the future.

3) Develop Mobile Apps
Big companies like Netfix, Trello, Linkedin, Paypal, Walmart, Ebay, Yahoo, Medium & NASA are using Node.js.
Why? The advantage of Node.js is that uses an event-driven, non-blocking input/output model, which means it can receive thousands of concurrent requests!
This means more job opportunities as more Business’s move towards using Node.js.

4) Node development has a bright future

“I get the clear impression, especially from cloud vendors, that Node is one of most important workloads running on everyone’s cloud. Node.js has also become the de-facto language as the world moves off into serverless just by result of being the first. That’s creating new ecosystem opportunities that all center around Node with new demands and new work for the development team to consider. But it also creates opportunities for other partners, tool vendors, people who work to essentially provide gateways to APIs and other things to make those assets available.”
[ Todd Moore, IBM Developer]

“Node.js is well positioned to continue growth in fueling the as-a-service paradigm and serverless programming. Those are two key areas where the Node community will grow because it’s fundamental to those two areas.” [Wade Olson – Program Director of the ACIT Cloud Studios]

“Node.js will continue its impressive growth in terms of both user acceptance and dev community, but users will demand continued focus on greater security, better resource utilization in memory and CPU, faster starting time, and similar core features.”  [Alex Pollitt is the Co-founder at Tigera]

“We’ve gathered data on 17 software languages/skills that we loosely selected based on perceived popularity and available data. So if you feel an important language or framework is missing do not hesitate to point this out. The 17 researched skills are (in random order): SQL, Java, Javascript, Python, .NET, C, C#, AngularJS, C++, PHP, ReactJS, Android, iOS, Ruby, NodeJS, Perl and Go.”
“Further, Javascript is probably mentioned in all job postings for Javascript-related frameworks such as NodeJS, ReactJS and AngularJS.”[]

Technical Advantages of Node.js

Why Node.js will make you a better developer.

  • Easy to learn – if you know JavaScript, it becomes easier to start using Node at the server side.
  • Is highly scalable – easy to scale the applications in horizontal as well as the vertical directions.
  • Ubiquity – the ability to run on the server and client side with the same code. You just have to write your code once.
  • Considered a full stack environment – it serves both the client and the server-side applications. You don’t need to hire two developers (front-end/back-end developers.)
  • Mobile App Development – with React Native, you can now write common code for both IOS and Android.
  • Large and active community (and growing).

There are many backend technologies that are used in web development today.
Besides PHP, some of the most popular are Ruby on Rails and Python.
Each has its pros and cons and functions well as a backend environment.

Node.js can be a successful platform for:

  • Web (front-end)
  • Mobile (Apps)
  • Back End

Which makes it a versatile development tool that can benefit every developer.
In addition, having Node.js on your resume can only help boost your chances with future endeavors!
