What is Boolean and what does it means in js width example?

 In JavaScript, a Boolean is a primitive data type that can hold one of two possible values: true or false.

Booleans are typically used in conditional statements to test whether a certain condition is true or false. For example, in an if statement, you can use a Boolean expression to test whether a certain variable is greater than another variable.

Lets look the example.

   

let x = 5;

    let y = 10;

    let isGreater = x > y;

    if (isGreater) {

        console.log("x is greater than y");

    } else {

        console.log("x is not greater than y");

    }

In this example, the Boolean variable isGreater is assigned the value false because x is not greater than y.

You can also use Boolean values in other types of expressions, such as logical operators (&&, ||, !) and comparison operators (==, ===, !=, !==, >, <, >=, <=) to create more complex conditions.

Booleans are also commonly used in conjunction with other types of variables, for example, you can check if a variable is undefined or null, or if an object has a certain property or method.

In summary, Boolean is a data type in JavaScript that can hold either true or false values, They are commonly used in conditional statements to check the state of the variables, objects or the conditions, and also to create more complex conditions using logical and comparison operators.
