Of course, there are people who skip the basics and start learning straight away from the React.js library, or even Node.js. This carries certain risks. You cannot build a good house without a solid foundation. But today we are going to talk about Node.js and its benefits.
Node.js is already used in development by such large companies as Netflix, Walmart, PayPal, Ebay, Yahoo, Uber and others. And every year their number is growing. Why has Node.js become so popular and why is it so loved?
One of the main advantages is that JS can be used both on the client side of the application and on the server side. That is, the Front-end and Back-end are written in the same language. And the programmer does not need to change the programming context during the development process. This means it is easier to learn and work.
Second, in spite of single-threading, the speed of Node.js is very high due to the asynchronous execution of I / O operations, and this does not block the operation of applications. You can read files, send emails, and do other things at the same time. And that means you save time on waiting until the completion of the previous task.
The third, centralized repository NPM (Node Package Manager) is a manager of ready-made modules. When working on a project, this helps to avoid writing the same components, which means it saves the development time of ready-made applications at times.
You can of course continue to list the advantages, but the main thing is that the Node.js platform is developing rapidly and meets all modern IT industry standards. The technology is firmly entrenched in the market and will be in demand.
There are two versions of Node.js: Current and LTS (long time support). LTS is a stable, tested version that is used for serious commercial projects. The Current version is always one step ahead in terms of functionality, but it is better to use it for personal or educational projects, since the version is unstable and subject to frequent changes, but contains all the innovations of the language. These are main node js advantages.
Node.js technology ranks second in popularity in the ranking of frameworks, libraries and platforms.
