Reasons Why Companies Use Node.js

1. JavaScript Framework

This in itself is a plus point because every developer knows at least a little JavaScript. It is a front-end language and is used to handle things on the browser only. So, before Node.js there were server-side languages available like PHP, ASP and many others. Everything was fine, but the only obstacles were configuration issues and environment support. If all was well under these conditions, then the architectural issues of slow response to requests were where response was taking a long time. Well, Node.js overcame all these issues and now supports the same environment throughout the application.

2. No Need of Maintaining Separate Threads – Single Threaded

?When using Node.js, the server does not need to maintain separate threads for each open connection. It requires almost no system resources to handle queries. It's single threaded and with just that thing, Node.js can do wonders. There are other server-side scripting languages like PHP, ASP.NET, Java, Ruby etc. But they all follow the multithreaded architecture. Now, as a reader, you must understand how such a complex thing is manageable in one thread? In response to this query, this is why Node.js is a wonderful framework that works asynchronously and acquires a unique method of event loop mechanism.

3. API Support with Handy Approaches

?As a technology explorer, when you decided to use JavaScript on the server and encountered problems with many data conversions. Node.js is the solution, it's one of those languages that doesn't require a developer to convert data for pre- and post-processed data if you're using Object Database (like MongoDB). NodeJS can be used to expose JSON objects with REST API and without any further issues the data is readable and writable. Using Node.js allows any developer to use the same language on client, server and database

4. Fast Execution

?Node.js is a JavaScript framework that runs on Google's V8 engine for use in Chrome. The V8 engine compiles code with extra smooth and fast speed. The fact that Node.js is fast is entirely due to the compilation of JavaScript into native machine code. Node.js simply eliminates unwanted wait time from the response request loop. The client side sends the request and if something takes a long time to process, well, it doesn't wait for the results and immediately moves on to the next request. When the result of the previous query arrives, it handles it at the same time.
