Our use of valueOf() is limited. The method is primarily used by the JavaScript engine, itself, to handle conversions in instances when a primitive is expected and the engine is given an object. The process is complex, and normally your application usually won’t have to be this extensive when testing a value. You’ll typically only need to test whether a variable has been set (typeof returns the correct data type), or find the length of a string in order to ensure it’s not an empty string. ==) elsewhere in the book.

Undefined')... But it’s not sufficient, because null variables have a typeof value equal to object. = 'undefined' && unknownVariable) ... Just listing the variable is sufficient to test whether it’s null or not. We still don’t know, though, if the variable is a nonempty string. length > 0) ... If the variable is a number, the test fails because a number doesn’t have a length. The String object and string literal variables succeed, because both support length. However, an array also succeeds, because the Array object also supports length.

12. Converting a Decimal to a Hexadecimal Value Problem You have a decimal value, and need to find its hexadecimal equivalent. toString(16)); Discussion By default, numbers in JavaScript are base 10, or decimal. However, they can also be converted to a different radix, including hexadecimal (16) and octal (8). toString(2); // value of 110111 binary To complete the octal and hexadecimal presentation, you’ll need to concatenate the zero to the octal, and the 0x to the hexadecimal value. Although decimals can be converted to any base number (between a range of 2 to 36), only the octal, hexadecimal, and decimal numbers can be manipulated, directly as numbers.
