  • ReactCasts #9 – Immutability in JavaScript

    In this episode I’ll talk about why immutability is important and how it can benefit you. I will draw some comparisons between JavaScript (which doesn’t treat data as immutable by default) and programming languages that have immutability built in. Finally, I will show how to make immutable operations in plain Javascript. Episode Source Code: https://github.com/cassiozen/ReactCasts/tree/master/episode9…

  • Arrow functions in JavaScript – What, Why and How – FunFunFunction #32

    Arrow functions are (pretty much) a shorter function syntax in JavaScript.
