What in Func in c#

    Func is a generic delegate that encapsulates a method that can accept parameters and return some value

//Annonymous function
Func MyFun1 = delegate(int[] a)
    {
        string tempString = "";
        foreach (int num in a) {
            tempString += num.ToString() + ",";
        }       
        return tempString;
    };



//Generic or Arrow function
    Func MyFun2 = (a) =>
    {
        string tempString = "";
        foreach (float num in a)
        {
            tempString += num.ToString() + ",";
        }
        return tempString;
    };

    private T[] Sort(T[] inputArray)
    {
        //Sort array
        //and return sorted array
        return inputArray;
    }

   int[] numArray = { 10, 15, 26, 98, 68 };
   float[] floatArray = { 10.9F, 15.5F, 26, 98.8F, 68 };
   lblMessage.Text = "Num : " + MyFun1.Invoke(Sort(numArray));
   lblMessage.Text += "Float : " + MyFun2.Invoke(Sort(floatArray));

Compare two dates in javascript

var yearDiff = 100;   
var d = new Date();
    var year = d.getFullYear();
    var month = d.getMonth();
    var day = d.getDate();
    var dtToday = new Date(year - yearDiff , month, day)

    mydate = new Date(DOBDate);
    year = mydate.getFullYear();
    month = mydate.getMonth();
    day = mydate.getDate();
    mydate = new Date(year, month, day);

    if (mydate > dtToday) {
      alert("Age can not be greater than 100 years.");
    }
    else {
        alert("Prev Smaller");
    }
