Date Format Validation in Javascript

There’re several different ways to handle Date values through the script, all depends on the exact need. In some cases, there’s a need to enter a date value manually, as text, yet to force it to be in a specific valid date format.

Below is the javascript code to valdate date with given format. Add this code inside the script tag


function ValidateDate(dt, format) {

    var isValid = true;

    if(dt.length != format.length) {
        isValid = false;
    }

    format = format.replace(/\ /g, "/").toLowerCase();
    dt = dt.replace(/\ /g, "/");
    var dateFormat = dt;
    //Get Day Value
    var day = 0;
    if(format.indexOf("dd") > -1) {
        var index = format.indexOf("dd"),
        day = dt.substring(index * 1 + 2);
      dateFormat=  dateFormat.replaceAt(index, "dd");

    } else if(format.indexOf("d") > -1) {
        var index = format.indexOf("dd"),
        day = dt.substring(inde, index * 1 + 1);
       dateFormat=  dateFormat.replaceAt(index, "d");
    } else {
        isValid = false;
    }

    //Get Month Value
    var month = 0;
    if(format.indexOf("mmm") > -1) {
        var index = format.indexOf("mmm"),
        month = dt.substring(index, index * 1 + 3);
      dateFormat=   dateFormat.replaceAt(index, "mmm");
    } else if(format.indexOf("mm") > -1) {
        var index = format.indexOf("mm"),
        month = dt.substring(index, index * 1 + 2);
       dateFormat=  dateFormat.replaceAt(index, "mm");
    }
    else {
        isValid = false;
    }

    var year = 0;
    if(format.indexOf("yyyy") > -1) {
        var index = format.indexOf("yyyy"),
        year = dt.substring(index, index * 1 + 4);
       dateFormat=  dateFormat.replaceAt(index, "yyyy");
    } else if(format.indexOf("yy") > -1) {
        var index = format.indexOf("yy"),
        year = dt.substring(index, index * 1 + 2);
      dateFormat=   dateFormat.replaceAt(index, "yy");
    }
    else {
        isValid = false;
    }

    if(dateFormat != format)
    {
        isValid = false;
    }

    console.log(day);
    console.log(month);
    console.log(year);
	console.log(isValid);

}
String.prototype.replaceAt = function(index, replacement) {
    return this.substr(0, index) + replacement + this.substr(index + replacement.length);
}

ValidateDate("12-07-2017", "MM-DD-YYYY");
ValidateDate("12-07-2017", "DD/MM/YYYY");
ValidateDate("2017-07-12", "YYYY-MM-DD");

FizzBuzz Problem Solution with C#

The "Fizz-Buzz test" is an interview question designed to help filter out the 99.5% of programming job candidates who can't seem to program their way out of a wet paper bag. The text of the programming assignment is as follows:

"Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”."

Method 1

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace TestConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            for (int i = 1; i <= 100; i++)
            {
                if (i % 3 == 0 && i % 5 == 0)
                {
                    Console.WriteLine("FizzBuzz");
                }
                else if (i % 3 == 0)
                {
                    Console.WriteLine("Fizz");
                }
