So far, we have learned how to tell the difference between various types and characteristics within JavaScript using detection. As we have seen, detection is useful when needing to provide alternative values or warnings in the case of unexpected or incompatible values. There is an additional mechanism for dealing with such values, however: we can convert them from the values we don't desire into the values we do desire.
In order to convert a value, we use a mechanism known as casting. Casting is the intentional and explicit derivation of one type from another type. In contrast to casting, there is also coercion. Coercion is the implicit and internal process of conversion employed by JavaScript when we use operators or language constructs that require specific types. An example of this would be when passing String values to a multiplication...
