Accessing Map Values
We can access the value corresponding to a key in a map using the following syntax:
index.go
For example:
index.go
The expression prices["apple"]
essentially references the memory location where the value 100
is stored; hence, it acts like a variable. Therefore, we can edit the value stored at that key using the =
operator:
index.go
We can use the same assignment syntax to create a new key in the map:
If the provided keyName
doesn't exist in the map, it will create and add a new key to the map with the assigned value.
index.go
Everything was clear?
