Changing a Variable in Go

Now that we know how to declare a variable in many ways, lets understand how to assignment works. In Go, use = for an assignment to an existing variable. The new value must be compatible with the variable’s type in The Golang Official Documentation

package main
 
import "fmt"
 
func main() {
	count := 10
	count = 20
	fmt.Println(count)
}

If you’ll run this, you’ll get 20
The first line count := 10 creates count then the next next count = 20 puts 20 in that same variable, so printing it gives 20 and then finally we are printing it
