+## Python
+
+```python
+def primeNumber(num):
+    if num <= 1:
+        return False
+    
+    for i in range(2, int(num**0.5) + 1):
+        if num % i == 0:
+            return False
+    
+    return True
+
+print(is_prime(11))
+print(is_prime(4))
+print(is_prime(1))
+print(is_prime(13))
+```
+
+## JavaScript
+
+```javascript
+function primeNumber(num) {
+    if (num <= 1) {
+        return false;
+    }
+    
+    for (let i = 2; i <= Math.sqrt(num); i++) {
+        if (num % i === 0) {
+            return false;
+        }
+    }
+
+    return true;
+}
+
+console.log(isPrime(11));
+console.log(isPrime(4));
+console.log(isPrime(1));
+console.log(isPrime(13));
+```
+
+## Explanation
+
+Both languages use a function that is called called "PrimeNumber" with an argument called "num" that a number in the code compares itself in order to see if it is an even number or not. They both use a .log system where you put in your arguments (or numbers) in order to see if they're a prime number or not.
+
+JavaScript uses console.log() in order to output files to the console, while python uses print() instead of console.log(). JavaScript uses the word "function" to create a function, while python uses the word "def" to create a function. Python create another function called "range" when creating a for loop, whereas JavaScript does not create another function.
