Can a goroutine write directly to another goroutine with a buffered channel?

In Go, channels are used for communication between goroutines, but they do not provide direct access for one goroutine to another's memory. Even with a buffered channel, one goroutine does not write directly to another — it sends data to the channel, and another goroutine reads from it.

A buffered channel allows the sender not to block immediately if the buffer is not full, but data still passes through the channel, not directly into another goroutine's memory.

Example:

dataCh := make(chan int, 2) // buffer of 2 elements

go func() {
    dataCh <- 1 // sending to the channel, does not block if buffer is not full
    dataCh <- 2
}()

val1 := <-dataCh // receiving from the channel
val2 := <-dataCh

Thus, communication occurs through the channel, not directly between goroutines.
