The toString()
method returns a string representing the specified object.
str.toString()
A string representing the calling object.
The String
object overrides the toString()
method of the Object
object; it does not inherit Object.prototype.toString()
. For String
objects, the toString()
method returns a string representation of the object and is the same as the String.prototype.valueOf()
method.

The following example displays the string value of a String
object:
var x = new String('Hello world'); console.log(x.toString()); // logs 'Hello world'
