What makes Node such a popular choice for many development projects?
One of nodes most compelling features is how it implements the concept on non-blocking I/O. Node embraces non-blocking I/O to improve performance for a number of application types.
Key strengths of Node
- Efficiently distributes small pieces of information
- Easily scales to multiple processors or servers
- standard library, module system, and npm
As with many software programming frameworks, you don’t necessarily need to be an expert in the programming language, but knowing enough of the basics stands you in good stead to mastering the framework, and over time you will master the programming language
C++, Java, C# or Python.
Node.js is a server-side framework, one of it’s main works is to handle any number of requests. In traditional I/O bound servers systems, a request can only be issued when the response to the previous request has arrived. This is typically referred to as blocking I/O.
Node.JS is a non-blocking I/O, If a request takes long time, Node.js sends that request in an event loop and moves on to handle the next request in the call stack. As soon as the pending request is done processing, it raises an event and the response is rendered on the browser.
In commonly in event driven architecture systems, servers perform tasks that might take a while to complete, like call an API or access a database. Node can process more incoming requests, allowing you to handle thousands of concurrent connections with very little overhead, as opposed to needing a thread on the server for each connection.
I recommend installing Node.js on your workstation using Node Version Manager (NVM), which enables you to easily install multiple different versions of Node on your workstations.
