3. Lambda

4. Lambda
 Anonymous Functions
 We need just one time
 Work with Higher Order Functions
 Haskell:
 Scala: () =>

5. Lambda

6. Higher Order Functions

7. Higher Order Functions
 Receive Function as parameters
 Return a Function as output
 FP Ground, composition and laziness
map
reduce
filter
fold
flat map
drop
exist
take
…

8. Higher Order Functions

9. Currying

10. Currying
 Transform: Chained Functions: Single arg
 Partial Application / Laziness / Composition
 Lambda calculus  Parallelism
 Some languages have nice syntax sugar

11. Let’s put some sugar on it…
