JS, TS, handle 3 consecutive ifs / ternaries
let textMessage = 'Next, select the '
switch (props.sceen) {
  case 'dd':
    textMessage += 'dd'
    break
  case 'ff':
    textMessage += 'ff'
    break
  case 'ss':
    textMessage += 'ss'
    break
  default:
    textMessage = ''
}


or 

messageDictionary = {
  dd: 'Next, select the dd ',
  ff: 'Next, select the ff ',
  ss: 'Next, select the ss '
}
textMessage = messageDict[props.screen] || ''


By using the second way, it will be easier for you to add the new screen option.
