Booleans, numbers, and strings all have a toString() method to convert their value to a string.

The Boolean toString() method simply outputs the string "true" or "false".

var bFound = false;
alert(bFound.toString());    //outputs "false"

The Number toString() method has two modes: default and radix mode.

In default mode, the toString() method outputs the numeric value in an appropriate string.

var iNum1 = 10;
var fNum2 = 10.0;
alert(iNum1.toString());     //outputs "10"
alert(fNum2.toString());     //outputs "10"

In default mode, the Number's toString() returns the decimal representation of the number.
