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?
