by ColorCode.io, Sina Jazayeri

This is episode 4 in a 10 part series I’m calling 10 things javascript developers should know but probably don’t. In this series, we’re going to cover some of the most fundamental and important parts of JavaScript that most of us don’t actually know, and barely touch. Today, for episode 4, we’re talking about Constructors and Constructor Functions, the idea behind them, the problem they solve, and how they're different from Factory Functions. Episode 4: Constructor Functions. Let’s go!
