In ES5, we only had one type of variable, var, but in ES6, we have three. types of variables: var, let and const. In this video, we explore the what, why, and how of var, let and const, and I also do a little lecture on the value of minimising mutable state.

💛 FUN FUN FUNCTION
Since 2015, Fun Fun Function (FFF) is one of the longest running weekly YouTube shows on programming 🏅 thanks to its consistency and quality reaching 200,000+ developers.
🤦♂️ The Failing Together concept is what makes FFF unique. Most coding content out there focus on step-by-step tutorials. We think tutorials are too far removed from what everyday development is like. Instead, FFF has created a completely new learning environment where we grow from failure, by solving problems while intensively interacting with a live audience.
Tutorials try to solve a problem. Failing Together makes you grow as a developer and coworker.
📹 Each show is recorded live on Twitch in a 2-hour livestream on Mondays. The host, assisted by the audience, is tasked to complete a programming challenge by an expert guest. Like in the real world, we often fail, and learn from it. This, of course, reflects what the audience identifies with, and is one of the most praised aspects of the show.
⏯ On Fridays, an edited version of the show is adapted for and published on YouTube.
