Maps in Go
A map is a very useful data type in Go.
In other language it’s also called dictionary or hash map or associative array.
Here’s how you create a map:
agesMap := make(map[string]int)You don’t need to set how many items the map will hold.
You can add a new item to the map in this way:
agesMap["flavio"] = 39You can also initialize the map with values directly using this syntax:
agesMap := map[string]int{"flavio": 39}You can get the value associated with a key using:
age := agesMap["flavio"]You can delete an item from the map using the delete() function in this way:
delete(agesMap, "flavio")download all my books for free
