'Shorter way to return propertype enum in typescript [closed]

I have a function like this:

  public CustomerEditType(customer: Customer): CustomerEditType {
    if (customer.company) {
      if (customer.vatNumber) {
        return CustomerEditType.COMPANYVAT;
      } else {
        return CustomerEditType.COMPANYNOVAT;
      }
    } else {
      return CustomerEditType.PRIVATE;
    }
  }

The problem I have here is I don't know how to make this function shorter. Maybe an inline return statement? How do I make this function shorter?

javascript typescript

Solution 1:^[1]

The shortest way would be:

// shortest method
public CustomerEditType(customer: Customer): CustomerEditType {
  return (customer.company) ? ((customer.vatNumber) ? CustomerEditType.COMPANYVAT : CustomerEditType.COMPANYNOVAT) : CustomerEditType.PRIVATE;
}

For more information see: Javascript one line If...else...else if statement

Solution 2:^[2]

public CustomerEditType(customer: Customer): CustomerEditType {
    return (customer.company? (customer.vatNumber? CustomerEditType.COMPANYVAT: CustomerEditType.COMPANYNOVAT) : CustomerEditType.PRIVATE));
}

Explanation: this is a short if else statement:

boolenaStatement? ifTrue : else

Using this way you can nest statements:

statement1? (statement2? statement2True: statement2false) : statement1False
