Initial value of type Vector3

Scripting
1

Can someone tell me how to assign an initial value to a variable of type Vector3?

C#:

using UnityEngine;
using System.Collections;

public class Question : MonoBehaviour {
	public Vector3 myVector3D = Vector3(1,2,3); // [B]<---- How to assign initial value for this?  [/B]
	
	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () { 

	}
}

Java Script;

var myVector3D : Vector3 = Vector3(1,2,3); // [B]<---- How to assign initial value for this?  [/B]
function Update () {
    ... 
}

public Vector3 myVector3D = new Vector3(1,2,3);
