Description

The game takes in three values: fizz, buzz, and stop. These values are retrieved from the >HTML page using the document.getElementById method and then parsed into integers using the parseInt function. The getValues function checks if the entered values are valid integers and if the stop value is less than or equal to 100. If the values are valid, the function calls the generateFizzBuzz function, passing in the fizz, buzz, and stop values as arguments.
The generateFizzBuzz function generates an array of values according to the FizzBuzz rules. It iterates from 1 to the stop value and checks if the current number is divisible by both fizz and buzz, in which case it pushes “FizzBuzz” to the array. If it is only divisible by fizz, it pushes “Fizz” to the array. If it is only divisible by buzz, it pushes “Buzz” to the array. Otherwise, it pushes the number itself to the array.
The resulting array is then passed to the displayFizzBuzz function, which takes in an array of values and displays them on the page. The function iterates over the array and creates an HTML string with a "div" element for each value. The class name of each "div" is determined based on whether the value is “Fizz”, “Buzz”, or “FizzBuzz”. The resulting HTML string is then added to the page using the innerHTML property of an element with id “results”. If the entered values are not valid, an error message is displayed using the SweetAlert library.
