What is Race Condition?
A bug that occurs when two operations happen at the same time and the outcome depends on which finishes first.
Why It Matters
Race conditions cause intermittent, hard-to-reproduce bugs that can corrupt data or produce incorrect results.
Real-World Example
Two users buying the last item in stock simultaneously, both succeeding because the inventory check ran before either purchase completed.
“Understanding terms like Race Condition matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
