In this file, we are adding and deleting 10 million elements in a map and see how it works.
package main
import (
"fmt"
"runtime"
)
func main() {
n := 10000000
m := make(map[int]*[128]byte)

A brief example of how we can achieve composition in go. Composition is not anything like inheritance it's just embed one struct to another to maintain data inheritance in it's own way.
// Person struct
type Person struct {
FirstName string
LastName string
Age int
TotalExperience int
}
// Person struct embedded in Job struct
type Job struct {

A brief example of how we can use principle of encapsulation in Go
package details
import (
fmt
person "github.com/nikzayn/encapsulation/user"
)
func main() {
fmt.Println(person.GetDateOfBirth()) // 1989
fmt.Println(person.getFoodStatus()) // Not declared by package because it is small caps
