Gigigo workshop

Motivation

• Reduce my mount stupid
• Learn functional concepts to use them with streams
• Problematize how FP can help us improve as programmers
• Get tools to analyze as a team if the FP is useful to solve our problems
• Generate an open debate
• Check how the FP is very related to the streams

Workshop Structure

• Core FP concepts in relation to OOP
• List operations
• Challenge (numbers, async numbers, post)
• Solve a problem in a classical way
• Solve a problem using FP concepts on improve steps
• How to use FP concepts with streams
• Debate (with practical demonstrations, NOT ALLOW ONLY THEORY)

Topics

• What is a paradigm?
• Why FP in JS?
• Why use streams?
• Why use FP?
• What is FP?
• Streams

List operations

• map
• reduce
• filter

Core concepts of the functional programing in comparison with the OOP

FP

• Few data structures many operations
• equational reasoning
• High order functions
• curry
• Point free style
• Referentional transparency(memoize)
• Composition
• Avoid side efects(inmutability)

OOP

• encapsulation
