 ## Learning objectives
 
-- Know how to define a variable.
-- Know how to update a variable.
-- Know that variable definitions can have type annotations.
-- Know how to define a module function.
-- Know how to return a value from a function (implicit return).
-- Know how to call a function.
-- Know how to define an integer.
-- Know how to define a string.
-- Know how to use mathematical operators on integers.
-- Know how to define single-line comments.
+- Know about use expressions.
+- Know they can be used to avoid indentation.
+- Know they can be used with any function that takes a function as a final argument.
 
 ## Out of scope
 
-- Naming rules for identifiers.
-- Generic values.
-- Memory and performance characteristics.
-- Anonymous functions.
-- Organizing functions in modules.
-- Public and private functions.
-- Documentation comments
+- Use expressions are block scoped, not function scoped like similar constructs in other languages.
+- Use with JavaScript promises.
 
 ## Concepts
 
-- `basics`: know what a variable is; know how to define a variable; know how to update a variable; know how to add type annotations for variables; know how to define a function; know how to return a value from a function; know how to call a function; how to define an integer; know how to define a string; know how to use mathematical operators on integers; know how to define comments.
+- `use-expressions`
 
 ## Prerequisites
 
-There are no prerequisites.
+- `results`
+- `anonymous-functions`
 
 ## Analyzer
 
 This exercise could benefit from the following rules added to the [analyzer][analyzer]:
 
-- Verify that the `remaining_minutes_in_oven` function calls the `expected_minutes_in_oven` function.
-- Verify that the `total_time_in_minutes` function calls the `preparation_time_in_minutes` function.
+- Verify that the `run_experiment` function uses `use` expressions.
