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.

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.
