5.7 Type system

Scala is statically typed. In other words, type checks are used for translation

time and not just at runtime instead of as with dynamically typed

Languages. Nevertheless, the typical disadvantage of static typing applies (i.e. the emergency

flexibility to indicate types everywhere) for Scala. Scala has a typinfe-

mechanism with which the type of an expression is in most cases

can be determined automatically. The places where a type is indicated

we have already discussed in Section 3.1.

Without going into the conflict, which sometimes escalates into a religious war,

static vs. Wanting to start dynamic typing remains

yet find that a large number of programming errors type errors

which are used by the programmer for static typing and dynamic

under certain circumstances can only be discovered by a user.
