Working with Golang Maps

Maps (also called dictionaries) are a very useful tool in helping to store and organize objects to be accessed in an efficient method. Most basic implementations of a map involve using a key to access a value in the map, resulting in key-value pairs, in which one key is associated with a specific value in the map. Within Go, maps follow this definition. This blog will cover the basic use cases of maps in Go, and how a newcomer to the language may utilize them for their applications.

Initialization

Initialization of a map can be done using the make command. This is similar to the initialization of a slice:

mapObject := make(map[string]string)

In this case, mapObject is a map that uses strings as a key to map to another string. When creating a map, the key type must be a type that is Comparable, or more specifically types that can be compared using the == operator. Examples of valid key types include booleans, numbers, strings and several other primitives can be used as keys. For reference on types, check out this link. One extra thing to note is that structs can be used as a key, provided that all the properties of the struct are Comparable.

Golang Map Example | Maps in Go Tutorial Explained

Golang map is an inbuilt data type that has keys that are unique within the map while the values may or may not be the same. The map data structure in Golang is used for fast lookups, retrieval, and deletion of the data based on keys; that is why it is one of the most used data structures in computer science. Go map is an unordered collection of key-value pairs. They map keys to values.

Golang Map Example

One of the most useful data structures in computer science is the hash table. Many hash table implementations exist with varying properties, but in general, they offer fast lookups, adds, and deletes. Go provides a built-in map type that implements a hash table.

Go provides another essential data type named the map which maps unique keys to values. A key is an object that you use to retrieve the value at a later date. Given a key and a value, you can store the value in a Map object. After the value is stored, you can retrieve it by using its key.

There are also other data types available unlike maps for example  arrays,  structs, and  slice in Golang. Let’s start our Golang maps tutorial.

Golang maps | Iterating over a Map | Golang Tutorial for Beginners

Iterating Over a Map.
You can iterate over a map using “range” form of the for loop. Its gives the key , value pair in every Iteration.
Map is an unordered collection and therefore iteration order of a map is not guaranteed over to be same every time we iterate.
Let me know if you have any questions in Maps.
