Why Daniel loves node.js so much
Why Daniel loves node.js so much? I believe that many inexperienced people have nothing to do about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.
I believe there are still many friends who don't know what node.js is, and many developers don't know what's going on, so as an IT man, why do I love node.js so much?
Why are those developers so crazy about node.js? First of all, it is necessary to understand what problems have been solved by the emergence of node.js. Before node.js, there were some bottlenecks in Web application architecture (including traffic, processor speed, and memory speed), which mainly refers to the number of concurrent connections that the server can handle. It was not until the emergence of node.js that this problem was solved perfectly.
Node.js changes the way you connect to the server, and each connection emits an event running in the process of the Node.js engine, rather than generating a new OS thread for each connection (and allocating some matching memory). Node.js does not produce deadlocks because node.js does not allow locks, let alone block Icano calls directly.
Let me tell you something about the advantages of node.js in my eyes. There are four main points:
① node.js is designed for network services with event-driven and asynchronous programming.
② node.js adopts IO processing in non-blocking mode, which can make node.js have excellent load capacity at relatively low system resource consumption, so it is very suitable to be used as a middle-tier service that depends on other IO resources.
③ node.js is lightweight and efficient, so it can be considered as the perfect solution for real-time application system in data-intensive distributed deployment environment.
It is very convenient for ④ to use node.js with CoffeeScript to write asynchronous operation chains. By contrast, it is not so natural for Tornado to write callbacks to named functions or to yield a Task.
After reading the above, do you understand why Daniel loves node.js so much? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
