// Predict and explain first BEFORE you run any code...

// this function should square any number but instead we're going to get an error

// =============> write your prediction of the error here: the error might be inside the function "the square number" or might be num is not identified.//

function square(3) {
    return num * num;
}

// =============> write the error message here: Uncaught syntaxError: Unexpected number.//

// =============> explain this error message here: This error occurs because the function parameter is not defined correctly. Instead of passing a number directly, we should use a variable name. In this case, we can use "num" as the parameter name.

// Finally, correct the code to fix the problem


// =============> write your new code here
// function square(num) {
// return num * num;
// }
