+# Prime Number Checker Assignment
+
+## Python Implementation
+
+```python
+def is_prime(n):
+    if n <= 1:
+        return False
+    if n <= 3:
+        return True
+    if n % 2 == 0 or n % 3 == 0:
+        return False
+    
+    i = 5
+    while i * i <= n:
+        if n % i == 0 or n % (i + 2) == 0:
+            return False
+        i += 6
+    return True
+
+# Example usage:
+print(is_prime(7))   # Output: True
+print(is_prime(10))  # Output: False
+
+## JavaScript Implementation
+
+```javascript
+function isPrime(n) {
+    if (n <= 1) return false;
+    if (n <= 3) return true;
+    if (n % 2 === 0 || n % 3 === 0) return false;
+
+    let i = 5;
+    while (i * i <= n) {
+        if (n % i === 0 || n % (i + 2) === 0) {
+            return false;
+        }
+        i += 6;
+    }
+    return true;
+}
+
+// Example usage:
+console.log(isPrime(7));   // Output: true
+console.log(isPrime(10));  // Output: false
+
+
+Differences
+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 lowercase true and false.
+
+Looping Structure
+
+Both use a while loop for efficiency, but Python relies on indentation for scope, while JavaScript uses curly braces {}.
+
+Output
+
+Python uses print() to display results.
+
+JavaScript uses console.log().
+
+Typing
+
+Python enforces stricter type rules.
+
+JavaScript allows implicit type coercion, which can lead to unexpected behavior if inputs aren’t carefully checked.
