+    if n < 2:
+        return False

+
+```JavaScript
+
+function isPrime(n) {
+    if (n < 2) return false;
+    for (let i = 2; i <= Math.sqrt(n); i++) {
+        if (n % i === 0) return false;

+    } else {
+        console.log(`${4} is not a prime number.`);
+    }
+
+
+```
+
+# Explanation
+
+---
+
+As seen above, I have created a code that helps the user determine whether a number is a prime number or not. I utilized both Python and Javascript to do so and this was my first time writing out my own code with those languages. The sample numbers **(3)** and **(4)** were used to show the reader, **you**, what an example of a prime number looks like. **Is_prime** stands for the command that determines whether a number **(num or n)** is prime or not. 
+
+## Similarities 
+
+- Both implementations display the number **(3)** as the prime number and **(4)** as the non-prime number. 
+- Both  use **"if"** and **"is_prime"** to point out if a number is prime or not.
+- Both implementations return **"true"** or **"false"** depending on whether the number is a prime number or not. 
+
+## Differences
+
+- The codeword used to determine the answer for the Java Code implementation is **console.log**.
+- The codeword used to determine the answer for the Python implementation is **print**. 
+- Python uses **def** before is_prime and JavaScript uses **function** before is_prime.

+### Bonus message from the creator: 
+Hello World! Again, this was my first time creating my own code. I had lots of fun working in JavaScript and Python, but would love to hear some good feedback or even complaints that you, the reader, may have. I spent a good **2 hours** trying to figure out how to get both Python and Javascript to work in a Markdown file. If any part of my code was confusing or uneasy to read, let a sista know! Happy coding! - A'nanatawa

+
+## Explanation
+
+Java uses a method called `PrimeNumberChecker` to check if a number is prime. The method is made up of two components. An `if` statement and a `for` loop. The `if` statement handles numbers that are less than 2. As the for loop then checks for divisibility from 2 to the square root of the number represented as int “i”. Both the if statement and for loop is nested within a public class `PrimeNumberChecker`
+
+JavaScript however is more straight forward. It uses a function called `‘isPrime’` that checks numbers that are less than or equal to 1. Once it does that, it returns false since the result would not be a prime number. Afterward an `if` statement is used, similarly to java. Then a `for` loop checks if the number is divisible by any number other than 1 and itself.  
+
+### Differences
+Biggest difference is that java because it is an object-oriented language has the method `‘PrimeNumberChecker’` in a class to use.
+
+### Similarities:
+Both languages use an if statement and a for loop to determine whether a number is prime or not.

+
+## Explanation  
+
+First I want to talk about a prime number. A prime number is a natural number only divisible by 1 and its self.
+
+Implementing it into code;
+
+
+The "Java" implementation uses a function named called IsPrime. This Method needs a number as an imput and checks if its prime. The first being if the number is less than or equal to 1. If the results arent a prime number the method is false. However it runs a loop starting from 2 to the sqrt of the number. Being that if the number is divisible by anything in that range the meothod will be false. if no divide then method is true.
+
+
+The "C++" Implementation also uses the function IsPrime. This function also works in a simimlar way then java. In thid method you need to first check if the number is 1 or less than, which returns false in that sense. After, the function literally loops from 2 up to the sqrt of the number simlar to java, looking for nay divisors. If i does find a divide then this method will return false. Concluding that if no divisor was found then menthod remains true.

+| **Input**             | Both take number input to check if output is prime.                           | Java has a personal writting style while C++ follows an ordered structure.|

+| **First Line of Code** | Both need a special line including designated tools for code to start and run. | Java starts with "public class;". C++ starts with "#include <iostream>"|
+| **Printing Output**    | Both Java and C++ use printing outputs to show if number is prime.          | Java uses "System.out.print()". C++ uses "cout" but, for larger programs uses std::cout to avoid potential name conflicts.|

+
+
+# Explanation
+After examining both languages I noticed that Python uses an is_prime (num) function that is used to dictate whether the number being input is prime or not. It uses specific clauses including numbers less than 1, even numbers greater than 2 , and numbers from 3 to the square root of said number for all statements to print false, otherwise it will print true if the number is equal to 2 as it is the smallest prime number and all others outside of said classes.  
+
+In Java it uses a class function primechecker and an isPrime(int num) to determine if a number is prime. Using if statements that will return false when numbers are less than 1, numbers that are even or greater than 2, and then uses a loop to divide from 2 to the square root of the number. If no divisor is found it will otherwise print true and if the number is equal to 2.
+
+
+
+
+# Differences
+In python, functions are defined using the def keyword, whereas in Java,  public class  is used as a keyword.
+Java uses “System.out.print” and python uses “print”
+Java uses a public static boolean while python uses def is_prime(num).

+# User Stories and Responses for Reddit 
+
+**Background:** Reddit is a website, mobile app, and social media platform that allows users to interact and comment within multiple communities and make photo-video-text content. Reddit utilizes upvotes, downvotes, and a point system, called karma, which is displayed on every profile. If your karma is low or negative (in the 100s or 1000s for example) it signifies to the reddit world that you are either a brand new user, don't use reddit often, or are an internet troll. If your karma is high (10,000+) it signifies that you have made viral, popular posts or comments in the past and, most likely, are a decent redditor. New users, or users with low karma, cannot comment or make posts on Reddit until their account is at least (1) day old. 
+
+---
+
+
+**User Story 1:**
+
+As a brand new reddit user, I want the ability to make a comment or post so that I can participate in the community conversation. 
+
+**Response/Acceptance Criteria:**
+- The update will allow new users to comment and post within communities even when their account is less than a day old. 
+- The system now incorporates a trigger word function that will auto-ban trolls when commenting or posting those words, but will allow new users with low karma to still make posts and comments.
+- The block against new or low karma users will be lifted from the website and mobile app, allowing anyone to interact on the website.
+
+
+**User Story 2:**
+
+I am a moderator that would like to respond to ModMail as myself, not as a Moderator, so that I can form a personal connection with the sender. 
+
+**Response/Acceptance Criteria:**
+- When the moderator enters the ModMail to respond to a message, there will be an option to respond anonymously as a "Moderator" or  as their personal account. 
+- The system will allow the moderator to craft their own private, additional message to the messenger that other Moderators cannot see or have access to.
+- The Modmail update will provide a checkbox that allows the Moderator to send an automatic friend request and inbox inquiry to the messenger so that the two people can form their own relationship. 
+
+
+
+**User Story 3:**
+
+I am non-frequent user that would like to have full access to the website so that I can participate in discussions quickly. 
+
+**Response/Acceptance Criteria:**
+
+- The software will allow users to comment as a "Guest" on reddit without needing to sign up to the website. 
+- The new update will allow Guest users to not only make their own posts, but also give them the opportunity to sign up and make their account official after making said post.
+- The website will now give the Guest user an option to add their cellphone or email address so that they get notified if anyone responds to their post.
