Why is Node.js our Favourite environment ever?

Node.js is typically used in real-time applications and APIs but recently many web developers are using it for web app development. What’s unique about node.js is that it allows you to take full control of your development all the way from server calls to frontend views. It is no surprise that Node.js is being used by companies like Microsoft, IBM, Cisco, Netflix and PayPal for its extreme speed, ease of use and high security. “Node.js powers our web applications and has allowed our teams to move much faster in bringing their designs to life?-said Jeff Harrell, Director of Engineering at PayPal In Node, while the file system is handling a specific request, Node uses the idle time to handle other requests. When the file system is done, it’s smart enough to tell Node to come take the resource and send to the browser. This is possible because of Node’s event loop. The event loop is basically a program that waits for events and dispatches them when they happen. One other important fact you might know is that JavaScript is single thread and so is Node. If you were to take a restaurant analogy, Node would be just one person serving food, no matter how many orders there is.
