The fear of git
Often times, Students/job seekers find git a overwhelming. I'm not sure if its the command line, all existing tutorials are complicated or not able to try and learn.
The importance of Git
Git is a fundamental tool which every aspiring engineer need to know and use daily. It is a widely used distributed version control system. Its open source and free. Git is designed to handle everything from small to very large projects with speed and efficiency.
Having basic knowledge of git is vital for freshers. Once you understand the basics, it becomes an incredibly powerful tool in your toolkit and its a skill you will use daily for a good foreseeable future.
Why should freshers/job seekers learn git ?
Once you join a company, most likely you will not be working alone in the code, There will be existing team members and also new joiners who would also work on the code. As a fresher, you will have collaborate with other developers and ensure everything goes smooth.
What could go wrong if you don't know git well?
Incorrect use of git could lead to:
Rework.
Overwriting changes of others.
Slowness of delivery.
Unhappy teammates/clients
Loss to business.
Enough said, let's move on.
Key features of Git
Below are some major features of git compared to other version control systems.
Its Distributed
Supports Branching & Merging
Data Assurance
Of course, Version Control
Has a staging Area and many more.
Branching
One of the features of git is branching. A branch is nothing but a light weight movable pointer which points to a "snapshot" of code. From this branch, we can create another branch by giving it a name.
Some important commands
git branch -a
git fetch origin
git branch -a
git switch <base-branch-name>
git pull origin <base-branch-name>
git switch -c mew-branch-name
Here is how I create a branch
Consider a scenario where I have to create a feature branch (A branch where a new feature would go) from develop (base branch) branch. Here is how I do it
git status
git checkout develop
git pull origin develop
git switch -c FEATURE_BRANCH origin/develop
Pull Request
After my changes are done and the feature is working (Automated Unit & Integration Tests), I raise a PR. A Pull Request.
So, A Pull Request (PR) is a way for developers to propose changes to a codebase to ensure the code changes work correctly without causing issues. You can read more about how to create a PR effective in this blog.
