You are developing a program for a bank that needs to **calculate commission** based on the transaction type. Your task is to write a `switch` statement that will output the commission based on the type of incoming transaction.

Commission rates based on transaction type:

- `Payment`: 0.5%;
- `Transfer`: 1.2%;
- `Withdrawal`: 2.0%;
- `Deposit`: 0.0% (no commission).

Replace `___` with the necessary code to compile it. Don't hesitate to check the **hint and solution** to understand the task better.

let transactionType: string = "Transfer"; // You can change the operation type
let commission: number;

switch (transactionType) {
    case ___:
        ___ = 0.5;
        break;
    case ___:
        ___ = ___;
        break;
    case ___:
        ___ = ___;
        break;
    case ___:
        ___ = ___;
        break;
    ___:
        ___ = -1; // Handle unknown transaction types
}

console.log(`Commission for ${transactionType}: ${commission}%`);

  1. In each case, you need to write the string name of the operation, the list of which you can see in the task description. <br/>
  2. Inside the <code>case</code> block, assign the correct commission value to the variable for each type of operation. If the operation is unknown to you, the commission should be <code>-1</code>.<br/>
  3. Don't forget about the <code>default</code> block.
