𝗚𝗶𝘁 𝘃𝘀 𝗚𝗶𝘁𝗛𝘂𝗯: What's the Difference?

Ever mixed up Git and GitHub? You’re not alone—they’re related but serve distinct purposes!

𝐆𝐢𝐭: A powerful version control system that tracks changes in your code. It’s your local toolkit for managing versions, rolling back changes, and collaborating.

𝐆𝐢𝐭𝐇𝐮𝐛: A cloud-based platform that hosts Git repositories online. It enhances collaboration by letting you share, review, and manage code—think of it as a social network for developers.

In short:
Git = Local version control tool
GitHub = Cloud-based hosting service for Git repositories

Understanding the difference can significantly improve your workflow and collaboration in software development!

What Is MERN?

MERN Stack is a Javascript Stack that is used for easier and faster deployment of full-stack web applications. MERN Stack comprises of 4 technologies namely: MongoDB, Express, React and Node.js. It is designed to make the development process smoother and easier.

MongoDB

MongoDb is a NoSQL DBMS where data is stored in the form of documents having key-value pairs similar to JSON objects. MongoDB enables users to create databases, schemas and tables.

ExpressJS

ExpressJS is a NodeJS framework that simplifies writing the backend code. It saves you from creating multiple Node modules.



ReactJS

ReactJS is a JS library that allows the development of user interfaces for mobile apps and SPAs. It allows you to code Javascript and develop UI components.

NodeJS

NodeJS is an open-source Javascript runtime environment that allows users to run code on the server.

How Git Works - From Working Directory to Remote Repository

[1]. Working Directory:
Your project starts here. The working directory is where you actively make changes to your files.
[2]. Staging Area (Index):
After modifying files, use git add to stage changes. This prepares them for the next commit, acting as a checkpoint.
[3]. Local Repository:
Upon staging, execute git commit to record changes in the local repository. Commits create snapshots of your project at specific points.
[4]. Stash (Optional):
If needed, use git stash to temporarily save changes without committing. Useful when switching branches or performing other tasks.
[5]. Remote Repository:
The remote repository, hosted on platforms like GitHub, is a version of your project accessible to others. Use git push to send local commits and git pull to fetch remote changes.
[6]. Remote Branch Tracking:
Local branches can be set to track corresponding branches on the remote. This eases synchronization with git pull or git push.
