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:
12345let 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:
1234let 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!
