Making Choices: Conditional Statements and Booleans

Conditional statements like [s]`[/s]if`, [s]`[/s]else if`, and [s]`[/s]else` leverage booleans to control program flow. The statement checks the boolean condition, and if it is [s]`[/s]true`, the corresponding code block executes.

[s]```[/s]

let age = 18;

if (age >= 18) {

console.log("You are eligible to vote!");

} else {

console.log("Sorry, you must be 18 or older to vote.");

}

```

[s]**[/s]The [s]`[/s]Boolean()` function:**

JavaScript provides the [s]`[/s]Boolean()` function, which can explicitly convert a value to a boolean. While often unnecessary due to implicit conversion, it can be helpful in certain situations.

[s]```[/s]

let userName = "";

if (Boolean(userName)) {

console.log("Welcome, " + userName + "!");

} else {

console.log("Please enter your username.");

}

```

By understanding booleans and their role in conditional statements, you unlock the power to make your JavaScript programs intelligent and dynamic. Remember, these tiny truth switches are the foundation for complex decision-making within your code. So, master the art of [s]`[/s]true` and [s]`[/s]false` to craft powerful and responsive web applications!
