String.prototype.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. Using toString() on a Number object returns the binary equivalent. Using parseInt().toString() on a String object returns the binary equivalent.

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'
