Node.js, by nature is single threaded. Hence it is not adviced to write CPU intensive applications

in Javascript and run them with Node.js due to performance impacts. But it is possible to overcome this

Node.js Addons are dynamically-linked shared objects, written in C++, that can be loaded into Node.js using

the require() function, and used just as if they were an ordinary Node.js module.
