Boolean method in javascript

     The Boolean() constructor function takes one parameter to be converted to a boolean value (i.e., true or false). Any valid JavaScript value that is not 0, −0, null, false, NaN, undefined, or an empty string(""), will be converted to true. Below, we create two boolean object values. One true, one false.

""  => empty string returns false value
"any val"  => string returns true value
3<4   => returns true
4<3  => returns false
null  => returns false

Syntax

     Boolean(condition);

Example

     alert(Boolean(3>4));
