Here in below example, variable employee is a map of string keys and int values. It creates an instance of map data type with keys and values.

In Golang, maps are created using make() and map() function with curly brackets and have keys and values. We will cover following in this tutorial to work with Maps in Golang. Maps are unordered and there are no fixed order in which the key/value pairs will be returned. If you want great documentation, you need to write great comments Godoc is only as. You can quickly navigate to our godocs below: coming soon coming soon coming soon. For all the details on Golang documentation, check out both the Golang Blog and GoDoc sites. A map data structure is used for fast lookup, retrieval and deletion of the data based on keys.Ī map is implemented using hash table that provides faster lookup on the data element using keys. Godocs are a great way to document your Go code. A key works like an index, pointing to the value associate with that key. New panics if any of the paths contain a leading slash. Map keys must be forward slash-separated paths with no leading slash, such as 'file1.txt' or 'dir/file2.txt'.

The maps are used to store and access values based on key. New returns a new FileSystem from the provided map. Golang maps are same like associative arrays, hash or dictionaries in other programming languages. Map in Golang is a data structure that provides an unordered collection of keys/values pairs. In this tutorial we will explain about Maps in Golang. This provides synchronized access to our map container, so that it can be used safely in a multi-threaded scenario.

In our previous tutorial, we have explained how to handle Marshalling and Unmarshalling in Golang. Another accepted practice is to use go’s sync.Map container.
