// Predict and explain first BEFORE you run any code...
//This code is to take one number function parameter and return  area.

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

// =============> write your prediction of the error here.
// syntaxError: passing an argument instead for a parameter.

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

// =============> write the error message here
//SyntaxError:Unexpected number

// =============> explain this error message here
//The function was not expecting number during declaration

// Finally, correct the code to fix the problem


// =============> write your new code here

//function square(num) {
 //   return num * num;
//}
//console.log(square(3))
