2. Conditional Statements

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!

Comparison Operators

If-else statement

3. Arrays

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.

Declaration and Advantages of Arrays

Working with Array Elements

Challenge: Modifying Arrays

4. Loops

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!

`forEach` method

5. Functions

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!

Introduction to TypeScript

Challenge (lottery)

Task

Gambling is bad, but it can be profitable for the casino owner and sometimes the players. However, you should only gamble with the extra money that you are willing to spend at the casino.

Your task is to write a function that determines the winner 🎉 and loser 😠 . Our lottery is very simplified, so the winner is the one who gets the number 2 or 7. There are a total of 10 options, meaning the number ranges from 0 to 9. The function should take one parameter, which is the number guessed by the player. If this number is a winning number, you should print 'Congratulations, you are now rich!' on the screen. If the number is not a winning number, then print 'Unfortunately, you lost, come back tomorrow'.

Feel free to peek at the hint or solution if you have any difficulties completing this task. We are all here to learn!


              1234567
            
function giveATry(___) {
    // write your implementation here
}

let randomValue = Math.floor(Math.random() * 10); // peeking a random number from 0 to 9
console.log(`You got the number ${randomValue}!`)
giveATry(randomValue)

¿Todo estuvo claro?
