## Overview

This repository is a collection of independent Go learning examples, not a single application: each directory contains a separate program illustrating a language feature. The clearest user-to-result flow is the UangMerah example, which reads an amount, computes and formats a discounted value, then prints it. Other sampled examples demonstrate concepts such as collections, pointers, interfaces, callbacks, and panic recovery. The README gives no further product description, and unsampled examples are represented only where their paths and topics are clear from the tree.

Main entry points: [`golang/UangMerah/hitung_persenan_umer.go`](https://github.com/bintangstilllerning/basic_golang/blob/main/golang/UangMerah/hitung_persenan_umer.go) (Discount calculator), [`golang/variadic-function/variadic.go`](https://github.com/bintangstilllerning/basic_golang/blob/main/golang/variadic-function/variadic.go) (Variadic sum), [`golang/anonymous-function/anonymousfunction.go`](https://github.com/bintangstilllerning/basic_golang/blob/main/golang/anonymous-function/anonymousfunction.go) (Blacklist callback), [`golang/function-asparameter/function_parameter.go`](https://github.com/bintangstilllerning/basic_golang/blob/main/golang/function-asparameter/function_parameter.go) (Function parameter)
