Python implementation

def is_even(number):
    return number % 2 == 0

# Example usage:
print(is_even(4))  # Output: True
print(is_even(7))  # Output: False

JavaScript implementation

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().
