JavaScript Date constructor Property

JavaScript Date constructor property returns the constructor function for an object. It is an ES1 feature and is supported by all browsers. The function which is returned by this property is just the reference to this function, not a date containing the function’s name. The JavaScript date constructor, string constructor, and boolean constructor return function Date() { [native code] }., function String() { [native code] } and function Boolean() { [native code] } respectively.

Syntax:

Date.constructor

Return value: function Date() { [native code] }.

The below example illustrates the JavaScript Date constructor Property:

Example 1:

JavaScript

let date = new Date(); 

console.log("Date.constructor:" + date.constructor);

Output:

Date.constructor:function Date() { [native code] }

Example 2: This example uses the constructor property and returns the date constructor function.
