What is Factory Function in JavaScript - in 1 minute

Factory Functions are an incredibly useful tool in JavaScript. It's a design pattern that's used in many languages. In this one minute coding video I will explain why they are useful, the problem they tend to solve, and a practical example. Enjoy!

I recommend you to make this kind of explanation, something short and concise is desirable by many people. :D

I recently implemented a strategy pattern, for rendering cards on a page. The rendering logic was a little bit different for each card. Then I used a factory to instantiate the different strategies and pass the correct strategy too the view, worked really nicely

I 'm still confusing, why people use constructor functions if exists factory. Factory functions more flexible: it's not reqired 'this' and 'new' keywords, haven't privacy issues and don't have a problems with losing context with 'this' when we have a nested functions. Can you explain in which cases we should use 'constructor' ?
