How Node Js Developer Works

Understanding Node js
Node js is a platform used to run JavaScript- based web applications. This platform will execute JavaScript code before the page appears in the browser. This platform was created by Ryan Dahl and was introduced to the public in 2009.

Node js is built with Google's V8 JavaScript engine , supporting the platform's ability to run JavaScript from the server side. In addition, Node js also has its own server library so developers no longer need to use other programs such as Nginx.

In programming language, node js developer works with the concept of non-blocking and single threaded . What is meant by non-blocking here is that the program algorithm will not stop at one process if the previous process does not require the results of the previous processing. This means that the program can still run even though one process has not been completed.

What is meant by single-threaded process is the ability list of italy cell phone numbers of this platform to process one process at a time. However, this platform also has an asynchronous mechanism so that it can work on several simple tasks simultaneously. To make it easier for you to understand the mechanism of how node js works, let's look at the following example.

Program A works with a blocking and multi-threaded system . When working, the algorithm of this program has several processes that must run. Because it is blocking, the algorithm of program A will not be able to continue if one process has not finished. In this system, threads are given to all processes whether they are active or not.

Next, there is a program B that is non-blocking and single threaded like in node.js. Although it has the same algorithm as program A, the performance of program B can continue even though one process has not been completed. In program B, threads are only allocated to active processes.

After looking at the example above, it can be said that program B works more efficiently when compared to program A thanks to its non-blocking and single thread nature .
