Things that are anew in Node.js 4.0

Node.js as a powerful run-time JavaScript environment has gone through a series of changes from its date of introduction. Every update, and changes made to the codes of Node.js have always given predominant scope for a Node.js developer to improve their creativity. The success story never ends with the recent update of Node.js to 4.0.0, as well. The release of this new version makes an attempt to include all the traits of io.js to Node.js, as well. Both these platforms follow different work schema, and developers have successfully done the mix-up of io.js and Node.js, and the new converged version of Node.js 4.0.0 has been launched. The project io.js works on a semantic version, and the converged version of Node.js is made to work on a semver scheme<major>.<minor>.<patch> to avert collisions with the main code line of Node.js. Anyhow, the project is successfully implemented.

Then...What will you find anew?

When developers use the new version of Node.js, they do not have to break the API alterations, to avoid it a simple path is provided. Google’s V8 JavaScript engine forms to be the base of both Node.js and io.js. The node 0.12 version was using 3.28x JavaScript engine, and in the new version of Node.js the latest version 4.5 is used.

Node.js projects are mostly created using native modules. Codes use C++ may usually clash with the V8, and thus end in the breaking of modules. The use of Nan, an abstraction library complete with Macros as well as various API will provide developers an absolute solution to avert these clashes. Build at least a module which makes use of Nan. Then your Node.js 4.0.0 projects will run smoothly. All the native modules developed previously should be redefined with Nan 2.x to function comfortably with Node.js 4.0.0.

Features that the new Node.js version support is many such as Block scoping with let and const, elaborate set of classes, and empowered Generators for future use. In shot, the existing ES6 gets extended with fantastic features for advanced functioning.

Perhaps the most important drawback of Node.js is the sluggish performance. With the addition of new traits, the functioning of Node.js is improved to 25%. Still, in most of the occasions we cannot expect it too be too fast, but the difference in performance is clearly visible while using Node.js 4.0.0.

Most importantly, Long term Support for the latest version was also implemented. We can expect the release of LTS versions in 12 months time. Once you start using the LTS version, you can depend on it comfortably for another 30 months. LTS support is one of the most important aspects of this new version, hence developers can find more details about it by referring to the devoted LTS sub-projects available on GitHUb, and even on Wiki page.

Summing up

An expert Node.js developer can start comfortably working with the new version without much difficulties. Small changes to the existing projects may help them, and it demands only proper maintaining for receiving the exclusive update of Node.js. It is worth to spend on Node.js 4.0.0 ,for it is capable of improving your website- building projects to a higher level.
