+### Writing some code
+
+For this assignment, you will need to write code that determines whether a number is a prime number. You will produce code in two different languages, then provide a 100+ word write up about the similarities and differences between the two implementations you made. An example is provided in the [anthonydmays/](./anthonydmays/) folder.

+## Python implementation
+
+```python
+def is_even(number):
+    return number % 2 == 0
+
+# Example usage:
+print(is_even(4))  # Output: True
+print(is_even(7))  # Output: False
+```
+
+## JavaScript implementation
+
+```javascript
+function isEven(number) {
+    return number % 2 === 0;
+}
+
+// Example usage:
+console.log(isEven(4)); // Output: true
+console.log(isEven(7)); // Output: false
+```
+
+## Explanation
+
+The Python implementation uses a function named `is_even` that takes a single argument `number`. It returns `True` if the number is even (i.e., when the remainder of the division of the number by 2 is zero), otherwise, it returns `False`.
+
+The JavaScript implementation uses a function named `isEven` that also takes a single argument `number`. It returns `true` if the number is even (using the same logic as the Python function) and `false` otherwise.
+
+### Differences
+
+1. **Syntax**: 
+   - In Python, functions are defined using the `def` keyword, whereas in JavaScript, the `function` keyword is used.
+   - Python uses `True` and `False` for boolean values, while JavaScript uses `true` and `false`.
+
+2. **Type Coercion**:
+   - JavaScript has type coercion, which can sometimes lead to unexpected results if the input is not properly handled. In contrast, Python is more strict with types.
+   
+3. **Function Calls**:
+   - The syntax for calling functions and printing to the console/output is slightly different. Python uses `print()`, while JavaScript uses `console.log()`.
