package main

import (

    "go.uber.org/zap"

)

func main() {

    // Create a logger

    logger, _ := zap.NewProduction()

    defer logger.Sync() // Flushes buffer, if any

    // Log some simple messages

    logger.Info("This is an info message")

 

}

defer logger.Sync() ensures that any buffered log entries are flushed before the program exits.
