In this post, I will share with you a quick tip to clear a map in Go.
There are two ways to clear a map in Go.
First way is by common sense, you can iterate through the map and delete each individual key one by one.
myMap := make(map[string]string)
...// assign some values and do something with map
// iterate through each key to delete
for key := range myMap {
delete(myMap, key)
}Another way to re-init the map by allocating a new map using make().
myMap := make(map[string]string)
...// assign some values and do something with map
// clean up
myMap := make(map[string]string)That’s it!
