String.prototype.toString()
The toString()
method returns a string representing the
specified object.
Syntax
toString();
Return value
A string representing the calling object.
Description
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. Using toString()
on a Number
object returns the binary equivalent. Using parseInt().toString()
on a String
object returns the binary equivalent.
Examples
Using toString()
The following example displays the string value of a String
object:
var x = new String("Hello world");
console.log(x.toString()); // logs 'Hello world'
The following example displays the binary value of a String
object:
var x = new String("13");
console.log(parseInt(x).toString(2)); // logs '1101'
The following example displays the binary value of a Number
object:
var x = new Number(13);
console.log(x.toString(2)); // logs '1101'
