How to Name Things in Go

Name Go identifiers using TitleCase for exported items and lowercase for unexported ones, matching the conventions seen in the standard library.

// Exported: visible outside the package
type Buffer struct {
	buf []byte
}

// Unexported: private to the package
func (b *Buffer) reset() {
	b.buf = b.buf[:0]
}

Use go fmt to automatically enforce these naming rules across your codebase.

In Go, capitalization controls visibility. If you start a name with a capital letter, it is public and accessible from other files. If you start with a lowercase letter, it is private and hidden from the outside world. Think of it like a house: capital letters are the front door anyone can use, while lowercase letters are the back door only you can access.
