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.

Questo corso è pensato per principianti assoluti che desiderano apprendere le basi del linguaggio di programmazione TypeScript. TypeScript è un linguaggio moderno e potente che estende le funzionalità di JavaScript, rendendo il codice più affidabile e leggibile. Inizieremo dalle basi, trattando variabili, tipi di dati, operatori di confronto e istruzioni condizionali. Successivamente, approfondiremo il lavoro con array e cicli. Al termine di questo corso, sarai in grado di creare semplici programmi in TypeScript e proseguire il percorso di apprendimento verso argomenti più avanzati.

This section introduces you to TypeScript. You will learn why TypeScript is valuable and how it differs from JavaScript.

We're going to take control of the code! In this section, you'll learn how to set conditions for code execution in TypeScript. You'll discover why this is used and how to use it correctly, so that your code becomes the envy of all top programmers!

Let's get acquainted with a convenient way to store data in a collection of elements - an array. You will learn how to create and use arrays, as well as how to add and work with elements in an array. An important and fundamental structure for any programmer.

Automate tasks with a large amount of data or variables. Loops will assist you in this, allowing you to process a large amount of data and quickly obtain results in just a few lines of code. We will explore the fundamental types of loops and teach you how to work with them effectively!

It's time to finally learn how to write your own functions that will perform the operations you specify. Functions will help you organize your code, breaking it into manageable pieces and calling them in a single line. It's time to learn!
