BAS here. I am pretty active in the TypeScript community. I'll be discussing JavaScript. I'm going to be talking about `this` and explaining the beauty (and simplicity) of prototype inheritance in JavaScript. It's going to be pretty code focused. I've found this to be the most mis-understood section of JavaScript. Also you'll understand why there is bind/call/apply on function prototypes (how they simplify your code). What's up with `constructor` and the simplicity of `instanceof`.
