The Boolean() constructor in JavaScript is a built-in function that can be used to create a new Boolean object. The Boolean() constructor takes a single argument and returns a Boolean object with a value of true or false depending on the type and value of the argument passed in.
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() { let value1 = Boolean(true); let 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 the Boolean constructor as a function
javascript
function func() { let value1 = Boolean("Hello"); let value2 = Boolean("0"); let value3 = Boolean(0); let value4 = Boolean(new Date()); console.log(value1); console.log(value2); console.log(value3); console.log(value4);}func(); |
Output:
true true false true
