Node.js is an open-source framework library for JavaScript. JavaScript is also open source, meaning they are both free to use.

What is Node.js?

Node.js is a commonly used JavaScript library and is an open-source, cross-platform JavaScript runtime environment. Node.js is among the most commonly utilized JavaScript libraries. It is far and away the most commonly used runtime environment in the professional sector, with Node.js being utilized by upwards of 98% of Fortune 500 companies. It allows users to create server-side architecture using JavaScript to build applications and webpages that constantly communicate information to server architecture without needing specific input from either the user or the server. This makes Node.js a vital programming language for any application that needs to be constantly connected to a server without needing to query that server at any given moment. For instance, it is part of the server architecture that allows users to stream video content on the internet without needing to download an entire video file. It is what allows online chat tools to function.

Node.js is also an integral tool in the continued development and refinement of the Internet of Things. More and more of our daily lives involve interacting with devices connected to the internet, ranging from our watches and phones to our cars and refrigerators. The various applications that these objects run to serve their niche functions tend to rely on Node.js to build the server environments and the asynchronous data processing events that allow multiple physical objects to be in meaningful conversation with one another over an internet connection. If you are using your voice to tell the virtual assistant on your desk to tell your thermostat to lower the temperature, Node.js infrastructure was likely vital in that exchange.

What Can You Do with Node.js?

Node.js is an incredibly versatile runtime environment that lets users construct virtually any program that seeks to use the functionalities of a webpage without needing to open up a web browser. This is vital for many web applications, such as almost all direct messaging programs and chatbot software. If you are designing an application and want to include a live chat feature, you will likely need to use Node.js. Node.js is also used for single-page web applications like Google Docs and Gmail. Even something as simple as including push notifications or scrolling news and weather updates in your application will require using Node.js.

Node.js is also a vital part of making the Internet of Things possible. Node.js is one of the key frameworks and runtime environments that allow sensors to detect changes and stimuli and relay that information to a device connected to the internet. This means that if you use the voice command on a digital assistant to tell your Bluetooth speaker system to lower its volume, you are using a program made possible thanks to Node.js. As this technology becomes more advanced and enters into sectors like the automotive and medical fields, skilled Node.js programmers will be able to construct complex, interconnected, potentially life-saving new technologies.

In-Depth Review of the Cost

Node.js is an open-source JavaScript library that is free to download and use. While there are paid services and hosting platforms that utilize Node.js, the code and framework are available through the Node.js website for anyone to download.

Why Learn Node.js?

Node.js is an incredibly versatile JavaScript library that is being refined and utilized in many different development sectors. It lets users build the backend server infrastructure that is necessary for applications that are constantly connected to and querying servers without the need for downloading new information. It is most commonly utilized in applications requiring real-time information exchanges between multiple devices and servers, such as content streaming applications or chatbots and other communication applications. It allows applications and webpages to run JavaScript functionalities outside a web browser that directly queries an HTML address. It is also used to make those applications more responsive to a wider range of stimuli, making it an essential tool for building virtual assistants, automated environmental programs, or other applications that utilize sensors to receive and interpret data.

Node.js is the largest JavaScript library in the world, and it is also by far the most used. Anyone looking to program complex applications, particularly those designed to run outside of a web browser, will want to learn how to use Node.js. As the devices we use in our daily lives become increasingly connected, the underlying software applications that allow those systems to operate will become increasingly more complex. As this complexity increases, the demand for skilled programmers will only continue to increase, particularly as the stakes of this development increase. The Internet of Things, wherein physical objects we take for granted are becoming increasingly interconnected, is becoming a more central fact of our lives. While the stakes are low with things like building programs that listen for your voice to turn on lights in a room, they are much higher for companies attempting to develop applications that gauge the speed of your car to detect whether or not you have been in an accident to call for emergency services. As these kinds of applications become more and more common, learning how to carefully and precisely utilize Node.js will be essential for engineers.
