Newbee question array/delay

Hi all, I'm new in JS (do have c experience) and I'm pretty well started with the Wiki adaption of Michael "LOSER" Gruhn's 1st Ever Jesusonic Tutorial ... However, I do not completely understand the use of buffers/arrays for e.g delay ... The part in the example that is not clear to me, goes like this: @sample bufpos[0] = spl0 ; bufpos = bufpos + 1 ; bufpos > echolength ? bufpos = 0; spl0 = spl0 + bufpos[0] ; spl1 = spl0 ; I would guess that bufpos[0] is the first element of an array in which the value of spl0 is written. But what does the instruction "bufpos = bufpos + 1" do? In c it would mean that the pointer of the array is increased but here, I don't know. I'm confused because in the condition, it says "bufpos = 0" ... Thanks in advance!

The biggest barrier for me in understanding JS was how the array works. There is only one array/buffer. Only one. Code:

You can actually use numeric constants as memory addresses too... Code:

0[index] is the same as mem[index] because mem, being undefined, is zero. Lotsa gotcha's in this package.

OK, thanks a lot guys, it becomes more clear now! I've noticed that some new code that I've written has a stereo input but a mono output! I intended to use 2 arrays but did I understood correct that this is mapped to the same array? Here is some code: bufpos0[RecCtr] = spl0; bufpos1[RecCtr] = spl1; spl0 = bufpos0[PlayCtr] * volume; spl1 = bufpos1[PlayCtr] * volume; If it's the same array, I can understand why the output is mono ...
