JavaScript Boolean() Constructor

JavaScript Boolean Constructor is used to create a new Boolean object. It can also be used alternatively for type conversion of another primitive data type to boolean 

Syntax:

Boolean(value)

Parameter: This constructor accepts a single argument 

• value: The parameter contains the value of the boolean

Below are examples of the Boolean Constructor property.

Example 1: In this example, we will create simple boolean values

javascript

function func() {
    var value1 = Boolean(true);
    var value2 = Boolean(false);
    console.log(value1);
    console.log(value2);
}
func();

Output:

true
false

Example 2: In this example, we will convert String, Number, and Date to boolean data type using Boolean constructor as a function

javascript

function func() {
    var value1 = Boolean("Hello");
    var value2 = Boolean("0");
    var value3 = Boolean(0);
    var value4 = Boolean(new Date());
    console.log(value1);
    console.log(value2);
    console.log(value3);
    console.log(value4);
}
func();

Output:

true
true
false
true
