Race Conditions
Explore race conditions in Go by understanding how concurrent goroutines can improperly access shared variables. Learn to detect these issues using the Go race detector and fix them by carefully managing channel operations and synchronization.
We'll cover the following...
A data race condition
A data race condition is a situation where two or more running elements, such as threads and goroutines, try to take control of or modify a shared resource or shared variable of a program. Strictly speaking, a data race occurs when two or more instructions access the same memory address, where at least one of them performs a write (change) operation. If all operations are read operations, then there is no race condition. In practice, this means that we might get different outputs if we run our program multiple times, and that is a bad thing.
