Introduction Version Control

What is Version Control

<aside> 💡 Version Control is:

• When we do our work with digital file such as .docx or if in programming .js /html. We might not be able to finish our work on that day. The work may length for days or even months.
• In those cases, those files must be managed and can be tracking for their changes that occurs in that file and it is called by Version Control.
• Example, if we commit manual version control is like this case:
  • Final_Examination.docx (Our final assignment for our dear lecture)
  • Final_Examination_v2.docx (After some review from our dear lecture)
  • Final_Examination_Fix.docx (Another fix-review from our professor)
  • Final_Examination_Fix_StopPlease.docx (Maybe last fixed exam)
  • Final_Examination_OhMyGod😭.docx (Final yeay) </aside>

<aside> 💡 Proceed:

• Actually, we can do alternative to overwrite our file.
• But when there is a bug / mistake in writing and it is quite far already (from start point), We cannot use the previous version.
• Then how do we if want to work with other people in the same file? </aside>

What is GitHub? or GitLab?

<aside> 💡 What is GitHub or GitLab

• After we can understand vcs that can be done in our local computer.
• If we want to store our code or our file on a host, it can be eased by using GitHub that is integrated with Git online and can be accessed from any local computer. </aside>

GitHub vs Git

<aside> 💡 GitHub is not same with Git.

• Git is an open-source version control system (a software)
• GitHub is a company that run service for hosting file on the internet using GIT system.

So, not only GitHub that utilizes GIT system.

Visualization

For example, in version 3 there is a bug. We need to go back to version 2

Therefore, version bug can be assumed not to use

Teamwork Case

1

For instance, we got another friend. Where he added another code.

2

After adding more code, our friend input that code into his Branch Code

3

Let’s say ours is version 2. While our friend code old version of version 1.

Our friend will need to push or request.

4

Then there will be Merged version. In first person or our computer. There will be “Branch Code.”

So, the new version will emerge.

Version Control System:

• Therefore, we need a system to ease us in having version control on our file.
• Version Control System create us to do tracking changes,undo changes ,compare version , cooperate with other people on a same file and many more.
• One of version control that commonly use is Git.
• The good news, Git is Free, it can be accessed from our computer for free and it is an open source. </aside>
