Document approach to typeof new use cases

[emilio-martinez]

The following use cases are confusing, and while uncommon, there needs to be an approach towards these decided as documented:

typeof new Boolean(true) === 'object'; 
typeof new Number(1) === 'object'; 
typeof new String('abc') === 'object';

• Write test cases
• Write documentation and reasoning behind approach
