Top 10 new features in Node JS –

Here are some of the most important features offered in the latest version of Nodejs-

First impression

Whenever you update software or a tool, you always have two things in mind. The first one is that what new features would you be able to see in this version and the Second thing is that for what time this version will be compatible. We will discuss its new features in the next points, but if we talk about the point of compatibility, then it is said that you won’t have to worry about it at all, as the latest version which is Node v12 will get support up to 2022, which is an excellent thing.

V8 engine

As cars have an engine that determines the overall performance of the car, the same is the case with these tools. Node v12 has the latest v8 engine with the help of which you would be able to work more efficiently on this tool.

Faster execution

As all the work is done on this tool is in the form of JavaScript, so the main challenge for the team was to create a type of engine that will offer faster execution of JavaScript for instant results. So with the all-new v8 engine, we can get the highest execution speed till now.

Memory Management

For higher speed and faster execution processes, the management of memory is highly important. With the support of the v8 engine, we would be able to get the best memory management technology for enhanced processing.

JIT-less engine

You must have seen that when you are dealing with a large amount of JavaScript at the time of execution, they lag the most, but with the help of Node v12 and v8 engine support, this is not going to happen again ever. This v8 engine has the power to free up the memory during the runtime process so that the project can work fluently without any lag. This happens because of Node v12’s ability to use the memory efficiently and ending up useless tasks during the runtime of the project.

WebAssembly Threads

This is a new feature that’s added in the Node v12, with the help of this feature you would be able to use WebAssembly threads which helps in defining binary codes on a non-Android device also. This will also help in making the system use more number of cores during any heavy usage. Before in the previous versions, users and app development company would have had to face several lags during runtime of a massive project.

ES6 Module Support

If you have some higher knowledge about JavaScript, then you must be knowing that JavaScript is wholly based on ECMA Script. ECMA scripts are the standardized scripts, so with the addition of the v8 engine in Node v12, you would be able to notice that, this tool supports the 6th version of ECMA scripts. With the help of ES6 support, your produced JavaScript would be supported by all types of web browsers, and hence the scripts would be more stable than ever.

Private Class Fields

As it’s clear from the name, you must have got that these are the type of variables which can be accessed within the class. You would not be able to access it from any external source or with the help of any other tool. After that, even if you tried to access it from an outside source, then you will face an error.

Startup Performance

The V8 engine is famous for it’s improved startup performance, and it also works well, but do you know how? So the basis of working with the help of which you get an enhance startup performance is, the Node v12 already generates all the data that is needed after the processing. So this clears up so high time-consuming steps and hence enhances the overall speed of startup performance.

New Compiler

In the latest update of Node v12, the company has introduced a minimum value system, this means that those who have the minimum requirement they would be only able to work with it. Before the system was working with no minimum requirement settings and because of which users had to face lags in their compiler. But with the help of the newly added compiler and minimum support platform those who have minimum requirement would be able to use this tool efficiently without any lag, while those who are not able to come up to a minimum requirement they would not be able to use this tool at all.

These were the top 10 most essential updates you can see in Node v12. But it’s not the end here yet, the company has added several essential features that we would not be able to cover in the Top 10 new features in Node JS list, so here are some other highly important changes they have made in the newer version.

  • You will be offered high security with the help of TLS 1.3 support, that you will notice in Node v12.
  • You still would have compatibility with the previous version of Node even after upgrading it to Node v12.
  • You would also be able to get diagnostic reports on demand.
