What is Node JS?
The reason behind a website being great and powerful is something called Node JS. It is majorly responsible for making the websites powerful while serving many other factors as well. Websites such as Uber, PayPal, etc. are some who use Node JS.
This article clearly explains what Node JS is, why, and how one should learn it, as well as the career opportunities after learning Node JS.
It has gained popularity because of the I/O programming model, which is nonblocking and event-driven. This model makes Node JS fast and light-weighted. It is best suited for-
- Building software
- Building applications
Both of which need coordinated interactions. Ex. Chatting apps.
Node JS gets its name from its use of building single process blocks called nodes. These blocks or nodes are then organized for communication and are scaled up to configure more extensive distributed programs.
Many startups and developers that use Node JS because it works with the Single-threaded Event Loop while handling multiple clients. Here is the makeup and usage of the Node JS in the sequence as follows-
- Event queue
- Thread pool
- Event loop
- External Resources
Firstly, the incoming request can either be elaborate or a simple web application, all according to the task one wants to execute.
Then the server-side platform, which is the Node JS server, takes up these incoming requests, processes them, and returns them to their user.
Due to the continuous inflow of requests, the event queue of the Node server has to store these, until it can pass these requests sequentially into the Event Loop.
The incoming requests from the clients can widely vary according to the task they want to perform, and this can be done by the different threads available in the Thread Pool.
Event Loop is where all the requests are received, worked on, processed, and then returned to their relevant user.
If some requests need to be blocked, it is done by the External Resources, which are used for computation, storing data, and the links.
Why Learn Node JS Course?
If you are wondering why you should consider learning Node JS at all and if it will be of any use to you, then here are some reasons that will make you feel positive about this program.
Single Thread Sufficiency:
Most servers require multiple programs to create many threads to handle the requests. But with Node JS, its Event Loop is what does the same work sequentially with a single thread without needing multiple threads.
The way that the Node JS server handles the incoming requests makes it use very fewer resources and memory compared to the other servers. And as the way of processing requests is sequential, that is one after the other, this also makes it lighter on the part of memory and does not load it up unnecessarily.
Perfect for Microservices
Traditional monoliths are now being done away with and are being widely replaced by microservices, which are much more agile and flexible. Node JS is very well suited for the building of microservices, which are sure to take over entirely, and that is why you should consider learning it.
Use beyond Web Development:
Node JS’s use is not restricted to only web development but goes so much beyond it. It is useful in OPS and infrastructure, also where it can be used to build support tools for software infrastructure and in IoT projects.
Career Opportunities After Node JS Course
The most important and inevitable question that comes up after you finish learning a particular course or whether you want to weigh your prospects before you discover it is what are the job opportunities after it.
After learning Node JS, there surely is a lot of scope for many job opportunities as it is a growing and widely used thing. Here below are some of the job opportunities that you can have should you choose to learn Node JS.
- Web design companies can hire you whether they work on large scale projects or are just getting started, depending on what you expect from your job.
- Many startups need their programs designed to boost their popularity and client base, and for that, your skills of Node JS would be in demand.
- Many major advertisement companies have switched over to Node JS, and that is where another job opening has been created for Node JS skills.
- Many Theme Development companies do not make their themes and thus need someone to use the Node JS skills and create themes.
- Product-based companies that need monitoring of the continuous inflow of requests by the users find the use of Node JS convenient and will hire you quickly with good pay even for a fresher.
