How to initialize a map with key-value pairs in Go?

To initialize a map with key-value pairs in Go, you can use the following methods:

Method 1: Using a Composite Literal

myMap := map[keyType]valueType{
    key1: value1,
    key2: value2,
    key3: value3,
    // add more key-value pairs as needed
}

Replace keyType with the data type of the keys and valueType with the data type of the values. Then assign key-value pairs within the braces {}.

Example:

myMap := map[string]int{
    "apple":  1,
    "banana": 2,
    "orange": 3,
}

Method 2: Using the make function

myMap := make(map[keyType]valueType)
myMap[key1] = value1
myMap[key2] = value2
myMap[key3] = value3

Create an empty map using the make function, then assign values to individual keys using the = assignment operator.

Example:

myMap := make(map[string]int)
myMap["apple"] = 1
myMap["banana"] = 2
myMap["orange"] = 3

Both methods will initialize a map with the provided key-value pairs. Choose the method that suits your specific use case and preference.
