if statement

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:

if (condition) {
	// code to be executed if the condition is true
}

For example:


              12345
            
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:


              1234
            
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!

Tutto è chiaro?
