How does concurrency work in Go and what are its memory implications?

Concurrency in Go is achieved through goroutines, which are lightweight threads managed by the Go runtime. This allows multiple functions to run simultaneously, improving performance. However, it also requires careful memory management to avoid issues like race conditions.

What are goroutines and how do they differ from traditional threads?

Goroutines are functions that can run concurrently with other functions. Unlike traditional threads, they are much lighter and managed by the Go runtime, allowing thousands of them to run simultaneously without significant overhead.

Can you explain what a race condition is?

A race condition occurs when two or more goroutines access shared data and try to change it at the same time. This can lead to unpredictable results and bugs, so it's important to use synchronization techniques like channels or mutexes to prevent it.

What tools does Go provide to handle concurrency?

Go provides several tools for concurrency, including goroutines, channels for communication between goroutines, and the sync package for synchronization primitives like mutexes and wait groups.
