1What is a channel in Go?
What is a channel in Go?
Resposta
A channel is a data type that enables communication and synchronization between goroutines. It acts as a typed conduit allowing sending and receiving values in a thread-safe manner. Use channels to share data between goroutines instead of sharing memory directly.
2How to create an unbuffered channel of integers in Go?
How to create an unbuffered channel of integers in Go?
Resposta
An unbuffered channel is created with make(chan T) without specifying capacity. It blocks the sender until a receiver is ready, ensuring strict synchronization. Use unbuffered channels for one-to-one communications requiring explicit synchronization.
3What is the main difference between a buffered and an unbuffered channel?
What is the main difference between a buffered and an unbuffered channel?
Resposta
An unbuffered channel blocks the sender until a receiver is ready (strict synchronization), while a buffered channel can store values up to its capacity before blocking. Buffered channels decouple goroutines and improve performance in some cases, but can hide concurrency issues. Use unbuffered for synchronization, buffered for throughput.
