Understanding Node.js is easy believe me

To understand how Node.js works, first you need to understand a few key features of JavaScript that make it well suited for server-side development. JavaScript is a simple language, but it is also extremely flexible. This flexibility is the reason why it has stood the test of time. First-class functions and closures make it an ideal language for web applications.

JavaScript has a bad reputation for being unreliable. However, this notion couldn’t be further from the truth. Actually, JavaScript’s bad reputation comes from the DOM’s unreliability. The DOM (docment object model) is the API (application programming interface) that browser vendors provide to interact with the browser using JavaScript. The DOM has idiosyncrasies between browser vendors. However, JavaScript the language is well-defined and can be used reliably across browsers and Node.js. In this tutorial, we discuss a few fundamentals of JavaScript followed by how Node.js used JavaScript to provide a highly performant platform for web applications. Other people complain about how JavaScript handles programming errors (it tries to make invalid code work). However, in such cases, the developers are really to blame, as they need to be careful when working with a highly dynamic language.
