About This Video
Learn functional reactive programming with RxJS in practice by implementing an application that interacts with the Slack API.
Develop two web applications with the help of functional programming libraries.
In the first section, you will learn how different functional programming libraries implement automatic currying, partial application, lazy evaluation, higher-order functions, promises, cloning, chaining, function composition, and immutable data structures. You will execute code in Underscore.js, LoDash, Lazy.js, Ramda.js, Immutable.js, Scala, Elm, PureScript, and ClojureScript.
In order to learn how to use functional programming libraries in depth, in the second and third sections you will learn how to implement two web-applications using LoDash and RxJS.
The third section introduces functional reactive programming using RxJS. Functional reactive programming deserves its own section, as it is a comprehensive topic providing you with a different developer experience from most of the other functional programming libraries. After learning the fundamentals of functional reactive programming and RxJS, you will learn how to put the theory into practice by implementing a web application. This web application uses the Slack API to monitor the activity of different Slack channels. Beyond submitting Ajax requests, you will also learn how to use web sockets to display live updates on your site using event streams.
