Native array methods

Hello there!

I'm using SC2 for several years but it's first time I decide to make my own plugin.

Well, to improve existing one a little..

I have experience to work with different programming languages (C++, Delphi, Pascal and some others) and my question is not about how to make some things in JS.

But I can't find some information about where some methods (functions, properties etc.) came from.

This is a particular example.

Plugin: Array

File: runtime.js

Where can I find description of this things: cx, cy, cz, forX, forY, forZ, arr, forDepth and some others? I've tried to search it in *.js files in html5 folder but no succeeded.

I see that we can write this.cx = this.properties[0]; and this will be a Width of our Array.

And for example var a = this.arr; what is arr? It seems to be smth. like a link to our array but where did we found such description and others?

Well, another example, what means this.forX = []; or this.forDepth = -1;

I hope you understand what I want to know. Maybe I just can't see things under my nose

Those variables are all entirely defined and used within that single file. If you don't know Javascript, it might be better to ask on a site like StackOverflow.com.

Well, thank you for your time, Ashley.

For now I can see that I just mix up in my head declaring and assignment.

Maybe I need to learn JS more, because I can't understand why we wrote for the first time

this.cx = this.properties[0]

instead of

var this.cx = this.properties[0]

I thought, that it is an assignment, just not declaration. It seems, that I'm not right..

That is normal Javascript style. In constructors, member variables are initialised simply by assigning a value to this.something.

This is already an object like var a = {}, so values can be assigned to a.something freely.
