All I did was search for Javascript constructor, instead Youtube gave me the best coding teacher.

From Javascript constructor Google search to the best teacher you could ever get. This was fun. Thank you.

Seriously... U did an amazing job at explaining this. It is an incredibly difficult concept to grasp if ur just searching around for the answer aimlessly and having to sort through a million different results. But u said something that set off a lightbulb in my mind and made it make more sense. They way I see it now is that a literal object is kind of like a "hard coded" object that gets used once. The way I see the constructor function is that it's a template that can be reused. One is a "use once" scenario. And the other one is a "multi use" scenario where u can plug stuff in. I could never understand why anyone would put a constructor function inside classes and now this clarified it a lot more than anyone was able to do for me before. So thank u!

You are an amazing teacher! You have the magical power to make coding energetic, fun and easy to understand. I particularly love how you use concept diagram/ drawing to explain the javascript concept instead of just simply typing the code. Thank you so much!

Daniel Shiffman. You are a great teacher and a awesome programmer. I love this new coding train thing you are doing. It's teaching lots of people to achieve what they want with their coding. I've seen you come so far. Peace.✌️

I decided to use the idea from the purple rain video to make a rain program with objects and arrays. Right now, it's a really basic program, but it works and I'm making it more complex and better organized the more I watch these videos. The videos help a ton, I hope I have a professor like this next year lol

I'm only 13 and want to program when i'm older and out of any tutorials this one is the best. Dan Shiffman is so awesome and can't wait to see more videos in the future!

"constructor" without mentioning a word about "class", that's new to me. I love it.

Many a times I do not understand a subject/concept at its first watch or glance but researching here and there, i come back to where i first sought that knowledge. This seems amazing but I'm a bit lost, however I will be back to comment again.
