# Golang Ordered Map

Golang Ordered Map is a `map` data structure that maintains the order of the keys.

It also supports JSON and YAML marshalling.

## Installation

```bash

go get github.com/nicolasparada/go-omap

```

## Usage

```go

package main

import (

	omap "github.com/nicolasparada/go-omap"

)

func main() {

	data := []byte(`{ "name": "John", "age": 30, "active": true }`)

	var unordered map[string]any{}

	if err := json.Unmarshal(data, &unordered); err != nil {

		panic(err)

	}

	var ordered omap.Map[string, any]

	if err := json.Unmarshal(data, &ordered); err != nil {

		panic(err)

	}

	json.NewEncoder(os.Stdout).Encode(unordered) // will print in undefined order

	json.NewEncoder(os.Stdout).Encode(ordered) // will always print: {"name":"John","age":30,"active":true}

}

```
