What happens when objects are added `obj1 + obj2`, substracted `obj1 - obj2` or printed using `alert(obj)`? What happens when objects are added `obj1 + obj2`, subtracted `obj1 - obj2` or printed using `alert(obj)`?
There are special methods in objects that do the conversion. There are special methods in objects that do the conversion.

For objects, there's no to-boolean conversion, because all objects are `true` in a boolean context. So there are only string and numeric conversions. For objects, there's no to-boolean conversion, because all objects are `true` in a boolean context. So there are only string and numeric conversions.
The numeric conversion happens when we substract objects or apply mathematical functions. For instance, `Date` objects (to be covered in the chapter <info:date>) can be substracted, and the result of `date1 - date2` is the time difference between two dates. The numeric conversion happens when we subtract objects or apply mathematical functions.

As for the string conversion -- it usually happens when we output an object like `alert(obj)` and in similar contexts. As for the string conversion -- it usually happens when we output an object like `alert(obj)` and in similar contexts.
