Re: Newbie Help with loops

i know very little if at all .js but i sure know your problem from
other languages

sorta simple conceptually once one get past the newbie stage of
staring at it

imageArray should be an array of "objects" each of which has both a
name and a content along with anything else you might want then you do
a lookup ~ usually first result of doing it that way is to try to
change the name which is also the key then you are stuck again but
what you do is just put a new object in the array with the new name
then null the previous one to keep it all clean

you are setting imageIndex = 0; if it wont fit - that is standard
array problem so see if you can find what is called a Vector as that
is common name for grow-able array

best solution for finding things is a Map ( tree map ) and you just re-
do the thing on a name change and put it back in the map and if
operation succeed then null the old one

how one would do a tree map in .js I dont even know where to start,
just google it and work on it
