JavaScript String constructor Property

Last Updated : 29 May, 2023

The String constructor property in JavaScript is used to return the string constructor function for the object. The function which is returned by this property is just the reference to this function, not a string containing the function’s name. The JavaScript number constructor, string constructor, and boolean constructor return function Number() { [native code] }, function String() { [native code] } and function Boolean() { [native code] } respectively.

Syntax:

string.constructor

Return Value: function String() { [native code] }
