Developers write code, but they also write about code. Take a moment to search the web for tutorials about any of the subjects you’ve learned so far in this course. You’re likely to find thousands of tutorials written by developers of all skill levels, but especially by junior developers—like you!
Your Challenge this week is to create a tutorial that explains how a specific regular expression, or regex, functions by breaking down each part of the expression and describing what it does.
Before you start, clone the starter code.

Regex or Regular Expressions are powerful patterns used to match, search, and manipulate text. Yet they are hard to master which is why I am creating a breakdown, that everyone can understand. They are widely used in various programming languages and tools for tasks such as data validation, pattern matching, and text processing.
The regex /^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w\s\.-]*)*\/?$/ is a pattern that matches a URL. It consists of various components such as anchors, quantifiers, grouping constructs, bracket expressions, character classes, the OR operator, flags, and character escapes. This guide will provide a comprehensive explanation of each component used in the regex pattern.

some scenarios require us to run a piece of code at a specific time of day, the following method allows us to do this:
function runAtSpecificTimeOfDay(hour, minutes, func)
{
const twentyFourHours = 86400000;
const now = new Date();
let eta_ms = new Date(now.getFullYear(), now.getMonth(), now.getDate(), hour, minutes, 0, 0).getTime() - now;
if (eta_ms < 0)
