The json:"omitempty" tag option in Go indicates that if a field has an empty value (the zero value for its type), it should be omitted from the JSON output. This tag option is commonly used when you want to avoid including fields with empty values in the JSON representation, making the JSON data more concise and meaningful. It's a useful feature for optimizing the size of JSON payloads sent over the network.
