            Why does React App appear twice on webpage?
            Asked 2021-Jun-13 at 21:42

            I created a React app based on Free Code Camp's Drum Machine project which works successfully on Code Pen and passes all tests found here https://codepen.io/kevin-orara/pen/RwKvjJz however when I transfer the code to Visual Studio it now fails 1 test. Yes the app appears to work and even compiled successfully. Now it is failing one test which is #6

            When I press the trigger key associated with each .drum-pad, the audio clip contained in its child element should be triggered (e.g. pressing the Q key should trigger the drum pad which contains the string "Q", pressing the W key should trigger the drum pad which contains the string "W", etc.).

            GitHub Repo here: https://github.com/korara78/drum-machine-fcc/tree/main/drum-machine-fcc

            There are two things I noticed which seemed odd. First I had to add this code to the index.html file just to get the code to compile successfully. Being new to creating React apps I've only had to add 1 div id on index.html files thus far.

            The issue you are running into here is related to how HTML and Javascript allows and handles input from the user. This is because a button input is not always in a 'focused' state read more here, and hence, Javascript is not receiving input events from the element as the button is not strictly receiving any.

            The way to resolve this issue is realistically through CSS. The method most commonly used is using a standard text input field as shown below which is autofocused and maybe as a listener to always re-focus the element incase the user clicks outside of it.

            The problem is this : in your handleKeyPress handler, const audio = event.target.children[0]; does not target the audio element.

            I have used ref to target the audio once user clicks on any of the keys mentioned in handleKeyPress. Also whenever we use onKeyDown synthetic event, we must use tabIndex={0}. Try the below code :)

            You can get your audio element by searching the DOM and then call .play() on it.

            for updating the state, you need to pass the function handleDisplay to DrumPad and call the handleDisplay inside handleClick, passing the required data as parameters.

            While string refs are discouraged. You can still use refs by using React.createRef

            ref: https://reactjs.org/docs/refs-and-the-dom.html

            You don't have to use refs even, you can give them all unique ids since they are unique anyways, and then whenever a key is pressed, you can check do a if q is pressed, add pressed class to the q button

            Adding and removing classes on an HTML element in JS can be achieved by the following:

            You can use element.classList.add("pressed") to achieve that. and element.classList.remove("pressed")
