6. Intro to Structs & Maps

Creating Structs Creating Instances of Structs Data in Structs What are Maps?Map Declaration and Initialization Accessing Map Values Deleting Keys From Maps Challenge: Creating a Structure

Introduction to GoLang

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
