I was about to complete the Drum Machine project, but an unexpected error was thrown while working.
I created the project with React + Redux, and after everything was done, unfortunately, the components did not render. I checked the console for errors and I saw this:
e represents the
event object, which I use for my event handlers. I don’t know why it is not a function.
I checked my code for errors and I believe there are none. Can someone tell me what I did wrong? Or is this a problem with CodePen?
