Hey, I think I figured out how to overload functions in js. Using fall through with || parameter evaluation, the bad being one has to arrange evaluation in a linear and logical way, limiting or complicating as a result. The "good", explicit range declarations. ie this(can take 0 to 5 parameters to execute and only 0-5 parameters with the usual unused extras, where as I could make it to take a dynamic no. of parameters) Jeff do good or bad thing?

Thank you so so so much! I have been struggling with this so bad. I read books, payed attention in class and i just couldn’t get the concept down. You explained everything so clearly in such a short time. More videos, please :)

One more thing: in JS, functions are a bit counter-intuitive; why do you think so many people have trouble with them? I think it will help if you spend more time helping them understand the logic. I know you get it, but your job is to help US get it. You tend to be breezing through all this.

This was very helpful, thank you! Being a beginner, sometimes I go so far down the rabbit hole that I forget some of the basic terminology.

Serious question, can someone give me a real example of a function from a website that someone created?

[atlaskaiser]

there is something i want to point out, for absolute beginners, it s necessary to clarify, for example, that the name of a function can be anything we wanna name it as long as it doesn't interfere with the rules of naming variables.

Always remember to repent of your sins (sin is transgression of YAHUAH The Father In Heaven’s LAW: Genesis, Exodus, Leviticus, Numbers, & Deuteronomy) And Have Belief On Yahusha The Messiah. HE Died and Rose three days later so that you can be forgiven of your sins!

HE Loves you! Come to HIM🙂🙂🙂🙂🙂🙂🙂🙂

Also, you need to turn up the volume for your vids: there are some of us who do NOT want to be leashed to our headphones and if you don't get that, then you can fk right off and we will move on and find someone else. I can barely hear you, and I have to keep going back and listen again; this is really annoying.
