You should use logical NOT operator in your console log sentence to check if isHappy. Here's the correct version of your code:
console.log(!isHappy)


// - Check if num is even and greater than 10 using the logical AND operator. Log the result to the console.
// TODO: ADD YOUR CODE BELOW

console.log(num % 2 == 0 && num > 10);

console.log(num % 3 == 0 || num % 5 == 0);

// TODO: ADD YOUR CODE BELOW

console.log(str.includes("e"));

// TODO: ADD YOUR CODE BELOW

console.log(str.endsWith("a"));
