I don't know if this will answer your question, but one reason you might have multiple return statements is if you want to return different values based on the result of a conditional statement. The following function is an example — it takes two numbers and returns the smaller of those two numbers.

function minValue(num1, num2) {
  if (num1 < num2) {
    return num1;
  }
  else {
    return num2;
  }
}
