I've been struggling with adding support for touch devices. The app works really well on desktop devices. So you can hover over the td element, then once you click and drag the td, the selection functionality is triggered, if the word is found the resultWords var then set it as marked, otherwise set selection to false.

There's a codesandbox for it: https://codesandbox.io/s/determined-turing-50zbpj?file=/src/index.js

I am trying to add the same functionality for the touch devices, so onTouchStart is supposed to add the first letter to array and once the swiping over td's is happening then keep adding the letters, word found -> set it as marked, otherwise -> set selection to false.

I have tried using onTouchStart combined with onTouchMove (all in the td element). onTouchStart seems to work fine, although onTouchMove always brings back the first letter where the gesture was first triggered.

Any suggestions how I could move on with this?
