Master Buffered and Unbuffered Channels in Go in 60 Seconds! #coding #golang #channel #concurrency

Want to understand how Buffered and Unbuffered channels work in Go? Let’s break it down in a quick 60-second guide!

We start with a simple program to print "Hello World!" using Go. But when we try to print asynchronously with a goroutine, we get no output. That's because the main goroutine finishes before the message is printed.

To fix this, we use an unbuffered channel that blocks until the receiver is ready, ensuring the message gets printed.

Next, we look at buffered channels, which allow the sender to continue without waiting, as long as there’s space in the buffer. However, exceeding the buffer size results in a deadlock.

Finally, we close the channel to ensure no more data is sent, helping prevent errors when the channel is closed.

That's how Buffered and Unbuffered channels work in Go!
