Summary  
The `if` statement is a control flow construct that evaluates a boolean expression and executes a block of code only when that expression is true, enabling conditional branching in code.

General domain of usage  
Access control via eligibility checks (e.g., age-based verification)

It's our turn to **control the code**; now we will set conditions for its execution!

Let's consider the most basic form of conditional statements - the `if` statement.

Let's move on to the syntax:
```javascript
if (condition) {
	// code to be executed if the condition is true
}
```
For example: 

let amIHappy = true;
if (amIHappy) {
	console.log('I am so happy!'); 
}
console.log("It's Monday");

That's almost all there is to it, but there's one more thing worth mentioning. Inside the `condition` block, there should be a `boolean` value. However, we can also place an expression that will result in a `boolean` value inside this block, for example:

let age: number = 22;
if (age >= 21) {
	console.log('You can buy alcohol');
}

You can change the value of the variable `age` to see how the code works depending on that value. 

I'll tell you how to set a condition if the first one doesn't work in the next chapter!

What will be the result of executing this code? 

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!
