Redux: Use const for Action Types
#100DaysOfCode
Learn the Dart programming language in this full tutorial for beginners. Dart is a strictly typed programming language that is used in the Flutter framework to develop cross platform mobile apps.
Since Dart supports both AOT (Ahead of time) and JIT (Just In Time) compilation, it delivers extremely fast development cycles and fast execution and startup times. It is a compiled programming language and can also transpile the code into JavaScript.

React: Render State in the User Interface Another Way
#100DaysOfCode
From the early days of the wild wild web, JavaScript has been there. Its evolved from a simple two week hack into a vibrant ecosystem that is continuously evolving to the modern web.
Join Matt as he walks the timeline of JavaScripts evolution from where it began into what it has become today. If you are new to web development or just getting back into development or coming to web development from a different part of the stack this is for you. Matt will showcase several demo apps that highlight the differences in how web apps used to be built with ES5 and highlight the tools that have changed how they are built for the modern web and ES6. Finally he will show how that same app can be built with Angular, one of the many modern frameworks that helps engineers build responsive and performant web applications.
Talk given by Matt Hippely at the JavaScriptLA meetup.
Thanks to JavaScriptLA for giving us permission to post this talk. freeCodeCamp is not associated with this talk. We're just excited to bring more exposure to to it!
