#Quick node http server code
The virtual machine can take the source code to compile it into the machine code at runtime. The virtual machine in Node.js (V8) which is responsible for executing JavaScript consists of a JIT compilation.JavaScript code is also executed in the process’ main thread while all other I/O operations are executed in separate threads which results in almost no delays. Although, one Node.js process would run at all times which would listen to the connections. Each request to the web-server won’t create a separate Node.js process.It also means that you can send emails, read files, query the database, etc. This means that all I/O operations don’t block any other operations. Node.js is asynchronous and single-threaded.Now, let’s have a look at a few points that will help us understand the secret behind Node.js’ speed. It’s the time spent on processing request which begins from the opening connection and ends when the client receives the response. In the context of web-services, execution speed consists of everything which is required for processing requests and to send a response to the client. The meaning of execution speed can range from Fibonacci sequence calculation to querying database. So, here we’ll try to figure out how is Node.js faster than the rest? First of all, it’s important to understand what ‘execution speed’ actually means. The first thing that comes to everyone’s mind when we talk about Node.js is the execution speed. Furthermore, we will also list out the top 5 best Node.js use cases. In this article, we are going to discuss each and every aspect of Node.js that makes it different from the rest of the JavaScript framework. This is probably the reason why big names like PayPal, LinkedIn, and Uber are using and praising the framework for its impressive performances. For starters, it has a large active community and it has an easy learning curve. There are many factors at play which makes Node.js so popular. Since its inception in the year 2009, Node.js has taken the world of web and application development by storm by emerging as the most popular development environment. If you are surprised by the popularity of Node.js? Then don’t worry, you’re not the only one.
