| ECMA Section: 9.2 Type Conversion: ToBoolean |
| Description: rules for converting an argument to a boolean. |
| undefined false |
| Null false |
| Boolean input argument( no conversion ) |
| Number returns false for 0, -0, and NaN |
| otherwise return true |
| String return false if the string is empty |
| (length is 0) otherwise the result is |
