Learn how to handle composition and build code to run your App in Functional javascriptAbout This VideoPure composition techniques that will help you deliver better codeUse a combination of combinators and generic containers to deliver powerful and fast codeInteract with your App successfully by linking eventsIn DetailIn this video we will learn techniques like combining smaller units of code intocomposition pipelines. Composition is functional programming's solution for taking smaller pieces of pure logicand building them into larger chunks of code which can also themselves be combined into even larger chunks. You'll learn how to reason about these composed functions and learn the laws of compositionality to deal with common issues that come along when writing compositional logic. Composing functions creates a form of functions called a “point-free” function.We'll continue building code that mirrors popular framework thinking. Students will learn how to create a statemanagement pattern like React and how to handle DOM events (and other I/O) by encapsulating logic insidegeneric containers. Show and hide more
