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!

Wow it felt so good just getting the run down of this - so many tutorial videos full of fluff but this is right to the point with a real world example! Thank you

[@ColorCodeio]

Glad it helped!

[@gpcgpc810]

Thank you for the 1 minute version, it is nice.

[@frostsmaker8966]

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

[@ColorCodeio]

Thanks!

Your contents is helping me a lot! Thanks so much.

Thank you

Wow, I could see these being used to create a blockchain

Is this something that we should do to refactor Em’s rainbow?! Also, happy to see a new 1-minute vid!

[@ColorCodeio]

Thanks, man :) There's going to be room for refactoring for sure, but I don't know if this particular pattern applies unless she's writing JavaScript.

[@jeckart3d]

@@ColorCodeio ahhhh, alright. I had thought what she was doing was based on JavaScript but in a “kid-friendly” wrapper.

[@ColorCodeio]

@@jeckart3d Yeah I remember there was an option to write actual JS or use the visualizer tool to make it easier. I wonder if there's a full JS engine behind that thing. Probably.🤷🏻‍♂️

[@HigkeyRegarded007]

mind blown.

[@PatrikRasch]

Quality.

[@mich_thedev]

Nicely explained. Is that how react's jsx. Elements are made?

[@mech-r4v]

You can just use class

[@killvapkillvaps3719]

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' ?

[@ColorCodeio]

Yep, explaining that in episode 5.

[@killvapkillvaps3719]

@@ColorCodeio thanks, will waiting for new episode)

[@yatin1370]

This was hugely helpful, understood the concept better. Thanks.

[@ColorCodeio]

Great!

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
