Buffering Behavior in Go Channels: make(chan bool) vs. make(chan bool, 1)
Unbuffered channels, created using make(chan bool), differ from buffered channels defined with make(chan bool, 1) in their ability to hold values.
Unbuffered Channels: make(chan bool)
Example:
<code class="go">chanFoo := make(chan bool) // Writes will block because no receiver is waiting chanFoo <- true // Corresponding read will now succeed even though no value was sent <-chanFoo</code>
Buffered Channels: make(chan bool, 1)
Example:
<code class="go">chanFoo := make(chan bool, 1) // Write will succeed immediately chanFoo <- true // Subsequent read will also succeed <-chanFoo</code>
Differences in Behavior
Practicality of Unbuffered Channels
While unbuffered channels may seem less intuitive or less useful, they have specific applications:
