Being a developer, there is always a possibility that you want to write everything from scratch when you develop an app or software.
There are a lot of developers that tend to create anything without using any framework, library or stack.
But using them has its own benefits.

I will focus on using **Stacks**, and focus especially on MERN Stack.
but first **What is a Stack?**

---
**"stack" is a set or combinations of programming languages or development tools and libraries and is used to simplify the process of developing complex software**

**What is MERN Stack?**
MERN stack is a Javascript stack, so based on the definition that we made above, MERN Stack is a set of Javascript Programming Languages, Libraries and Frameworks and related.
M - Mongo -> Database
E - ExpressJS -> Needed to Write Rest API Calls
R - ReactJS -> Frontend
N - NodeJS -> Backend

### MERN more a Fullstack Development Stack rather than a Frontend or Backend Development Stack

All its components are open-source. It is similar to MEAN but the Frontend Development Language used for **MEAN** is AngularJS while for **MERN** is ReactJS.

**3 Main Benefits of using MERN**
- Simplify the process of development for modern web applications. Makes the lifer easier for developers.
- It is widely used, very popular and consists on a set of great technologies like NodeJS, Mongo, React, Express and helps developers expanding their knowledge
- It is pure Javascript, so no need to know other technologies as PHP, Java etc..

***and It is pretty cool to work with.***
