The helloWorld captures the first two arguments into local variables txt1 and txt2, then shifts them off, storing the remaining function arguments ($@) in the rest variable. It then echos the variable values, surrounded by single quotes:

function helloWorld() {
  local txt1=$1
  local txt2=$2
  shift; shift
  local rest=$@
  echo "Hello World!"
  echo "  text 1: '$txt1'"
  echo "  text 2: '$txt2'"
  echo "    rest: '$rest'"
}
