+## Python implementation
+
+```python
+def is_prime(number):
+    if number <= 1:
+        return False  # Numbers less than or equal to 1 are not prime
+    # Check divisibility up to the square root of the number
+    for i in range(2, int(number ** 0.5) + 1):
+        if number % i == 0:  # If number is divisible by i, it's not prime
+            return False
+    return True  # If no divisors were found, the number is prime
+
+
+# Example usage:
+num = int(input("Enter a number: "))
+if is_prime(num):
+    print(f"{num} is a prime number.")
+else:
+    print(f"{num} is not a prime number.")
+
+```
+## JavaScript implementation
+
+```javascript
+function isPrime(number) { if (number <= 1) {
+        return false; // Numbers less than or equal to 1 are not prime
+    }
+    for (let i = 2; i <= Math.sqrt(number); i++) { // Check divisibility up to the square root of the number
+        if (number % i === 0) {
+            return false; // If number is divisible by i, it's not prime
+        }
+    }
+    return true; // If no divisors are found, the number is prime
+}
+
+// Example usage:
+let num = parseInt(prompt("Enter a number:"));
+if (isPrime(num)) {
+    console.log(num + " is a prime number.");
+} else {
+    console.log(num + " is not a prime number.");
+}
+```
+## Explanation
+
+The Python implementation uses a function named `is_prime` that takes a single argument `number`. It returns `True` if the number is prime otherwise, it returns `False`.
+
+The JavaScript implementation uses a function named `is_Prime` that also takes a single argument `number`. It returns `true` if the number is prime (using the same logic as the Python function) and `false` otherwise.
+
+Both implementations uses `num` and the strings: `"Enter a number"`,`"is a prime number"`&`"is not a prime number"` in the 
+code.
+Both implementations uses `if`, `else`, `for` and `return` to make the code function correclty.
+
+### 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`.
+   - Python uses `int (input())` to allow the integer input, while JavaScript uses `parseIn(prompt())`.
+
+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()`.
