In this shot, we will learn how to initialize a map in Golang.

A **map** is an unordered collection of key-value pairs, where the keys are unique.

We can initialize a map in two ways:
1. By using `make`
2. By using `map` literal

# 
#  1. Using `make`
We can initialize a map using the `make` function provided by Golang.
##
## Syntax
Initializing without size:
```
m := make(map[string]int)
```
Initializing with size:
```
m := make(map[string]int, 10)
```
Here, the key is of type `string`, and the value is of type `int`.

>Note: Providing the size here doesn't mean that `map` doesn't grow. It only allocates the given size, but the size will grow if we add more elements to it.

package main

//import format package
import(
  "fmt"
)

//program execution starts here
func main(){

  //initialize map using make
  m := make(map[string]int)

  //add an item
  m["apples"] = 20

  //display the map
  fmt.Println(m)
}

# 
## 2. Using `map` literal
We can initialize a map using the `map` literal provided by Golang.

## Syntax
```
m := map[string]int{"key":value}
```

Here, the key is of type `string` and the value is of type `int`.

We can provide key-value pairs, separated by the comma `,` in flower braces `{}`.

package main

//import format package
import(
  "fmt"
)

//program execution starts here
func main(){

  //initialize map using map literal
  m := map[string]int{"oranges":30}

  //display the map
  fmt.Println(m)
}

How to initialize a map in Golang

Initialize a map in Golang using `make` or map literals (`map[string]int{}`). Use `make` for optional size specifying.
