Why Version Control Exists ?
Before Git and GitHub, developers shared code the hard way.
Pendrives. Emails. ZIP files.
The Pendrive Era
A typical workflow looked like this:
- Copy code to a pendrive
- Give it to another developer
- They modify it
- Send it back as
software_v1,software_v2, orsoftware_latest_version
Everyone did this. And everyone suffered.
What Went Wrong
- One person overwrote another changes
- Nobody knew who changes what
- Bugs appeare with no history to trace
- Working code was lost forever
- Collaboration slowed instead of speeding up
If two developers edited the same file, one of them lost work. Always.
The Real Problem
No history. No ownership. No safe collaboration.
Why Version Control Became Necessary
Version control solved the chaos:
- Every change is tracked
- Nothing is lost
- Multiple developers can work safely
- You can go back in time
