reflect.ValueOf() Function in Golang with Examples
  • Last Updated : 03 May, 2020

Go language provides inbuilt support implementation of run-time reflection and allowing a program to manipulate objects with arbitrary types with the help of reflect package. The reflect.ValueOf() Function in Golang is used to get the new Value initialized to the concrete value stored in the interface i. To access this function, one needs to imports the reflect package in the program.

Syntax:

func ValueOf(i interface{}) Value

Parameters: This function takes the following parameters:

  • i: This parameter is the interface.

Return Value: This function returns the new Value initialized to the concrete value stored in the interface i.

Below examples illustrate the use of above method in Golang:

// Golang program to illustrate
// reflect.ValueOf() Function
   
package main
   
import (
    "fmt"
    "reflect"
)
   
// Main function
func main() {
   
    a := []int{2, 5}
       
    var b reflect.Value = reflect.ValueOf(&a)
   
    b = b.Elem()
       
    fmt.Println("Slice :", a)
       
    //use of ValueOf method
   
    b = reflect.Append(b, reflect.ValueOf(80))
    fmt.Println("Slice after appending data:", b)
   
}
