package builtin
The delete built-in function deletes the element with the specified key (m[key]) from the map. If m is nil or there is no such element, delete is a no-op.
Golang builtin.delete() function usage example
package main
import "fmt"
type Person struct {
Age int
}
var personmap map[string]Person
func main() {
personmap = make(map[string]Person)
personmap["Adam"] = Person{36}
fmt.Println("Before delete : ", personmap)
delete(personmap, "Adam")
fmt.Println("After delete : ", personmap)
}
Output :
Before delete : map[Adam:{36}]
After delete : map[]
