JavaScript React Basics (2018) Understanding State Bind Event Handlers to Components

These exercises use onClick. But what if you wanted to make sure the counters are accessible using a keyboard?

I hesitate to always use onClick for functionality because many times, I don't use a mouse. So, is there some other way to code this that allows for keyboard access to the score counters etc?

The "onchange" event Lukas mentioned will work for typing into input elements. But if you want to detect keyboard events on other elements or the document itself, you can use the "onkeydown" event.

See the MDN page on keydown for more details.

onChange, onFocus (or onFocusIn), and onBlur based on what you're trying to accomplish and when

Thanks! I also realized that I see a lot of onmouseclick - which thankfully is not used as often anymore, but a lot of older code I've seen still assumes use of a mouse.

I know this is an old question but in case people read this in the future, the "enter" or spacebar keys register as a click on the focused item, so onClick still works. Maybe this wasn't the case in 2019? I'm not sure about that.
