Check if a Number is Even or Odd
In this challenge, you will write a function that determines whether a given number is even or odd.
This is a fundamental problem in programming and can help users understand how to work with conditionals, functions, and the modulus (%) operator.
An even number is any number that is divisible by 2 without a remainder (e.g., 2, 4, 6, 8), while an odd number is any number that leaves a remainder of 1 when divided by 2 (e.g., 1, 3, 5, 7).
The function should:
Accept a single integer as input. Return "even" if the number is even, and "odd" if the number is odd.
Handle both positive and negative numbers. Assume the input is always a valid integer (no need to check for non-numeric values).
Example usage:
console.log(checkEvenOrOdd(10));// Expected output: "even"console.log(checkEvenOrOdd(7));// Expected output: "odd"console.log(checkEvenOrOdd(-4));// Expected output: "even"
