-# Why nodejs
+# Why Node.js
+
+* Node.js is OpenSource
+* Guarantees ease of scaling applications vertically by adding new resources to the existing node and horizontally with the addition of new nodes
+* It facilitates building separate components that easily complement larger applications, which means saving money at the initial development stages and potentially shortening time-to-market, reusable code (some of the code can be used both on the front and backend)
+* Tested on production (a lot of [companies use it](https://selleo.com/blog/10-successful-companies-using-nodejs) from the very beginning in 2009)
+* offers improved performance thanks to Chrome’s V8 engine
+* using JavaScript on both backend and frontend makes Node a great choice to improve speed and simplicity of implementation

-# Commonjs vs esm
+# CommonJS vs ESM
+
+The CommonJS module system, on the other hand, is built into Node.js. Before the introduction of the ES module in Node.js, CommonJS was the standard for Node.js modules. As a result, many Node.js libraries and modules are written with CommonJS.
+
+The ES module format was created to standardize the JavaScript module system. It has become the standard format for encapsulating JavaScript code for reuse.

-# Global keyword
+# global Keyword
+
+In browsers, the top-level scope is the global scope. This means that within the browser var something will define a new global variable. In Node.js this is different. The top-level scope is not the global scope; `var something` inside a Node.js module will be local to that module.
