✨ Golang Maps: Announcement and preparation
explained
What is the map of Golang? Why is it useful? How do you compare a slice? How to announce a map? How do you prepare the map? Don’t be afraid to answer all these questions in this friendly introduction to one of the most powerful Go.
Call what you like – HASHES, dictionaries, interconnected matrices, or, in He goes language, maps– This type of data structure is familiar to every programmer:
🔗What is the map of Golang?
The type of map data is integrated in Golang, so we often use it. Basically, it allows us to store some value (like 1.75 The value in the above example) and its recovery by searching for a key (He loves eggs).
Why is this useful? Well, there will be another way to store a set of relevant data values in slice:
menu := ()float64Full ArticleThis is not comfortable to deal with it because we can only recover the value through index (0, 1, 2, 3, etc.), or by looking at every value, in turn, to see if the ones we want. We cannot link values to other things. For example, which of these values corresponds to the price of eggs? It is impossible to know.
In contrast, the map allows us to take one set of things (eggsand baconand sausage), And preparing individual correspondence (a Mapping) With another set of things (1.75, 3.22, 1.89). More convenient when we want to search for the price of eggs, for example.
