Epic Skills Assessment Fictional Programming Language Logic 5

Question 1

In FictoScript, the `freeze` function applied to a list will:

Accepted Answer

Make the list immutable so no elements can be added, removed, or changed

Answer

`freeze` locks a data structure, making any subsequent mutation attempts raise a FrozenError.

Question 2

Which FictoScript feature allows a single function name to behave differently based on argument types?

Accepted Answer

Overloading via `fn/type` dispatch

Answer

FictoScript supports type-based dispatch by defining multiple `fn/type` signatures under the same function name.

Question 3

A FictoScript `lazy val` is evaluated:

Accepted Answer

Only the first time it is accessed, then cached

Answer

`lazy val` defers computation until first use, then memoizes the result so subsequent accesses are instant.

Question 4

In FictoScript, what does `filter(fn(x) => x mod 2 == 0, [1, 2, 3, 4, 5, 6])` return?

Accepted Answer

[2, 4, 6]

Answer

`filter` keeps only elements where the predicate returns true; here, even numbers pass the `mod 2 == 0` check.

Question 5

FictoScript's `trait` keyword is most similar to which concept in other languages?

Accepted Answer

An interface or mixin that defines behavior a type must implement

Answer

A `trait` defines a set of method signatures (and optionally default implementations) that types can adopt.
