Hi all,
I have a question on the efficiency of iterating through an object. I am
making a small dictionary web-app. The dictionary contains ~5000 words.
On start-up I get the entire list, indexed by letter, from the server and
store it in memory. The list comes as a JSON object that looks like:
{
"A" : {"1234" : "an A word",
"1235" : "another A word"},
"B" : ...
"C" : ...
(..)
"Z" : ...
}
Here the "1234" etc are unique ids required for querying the definition of
the word.
Once I have the list, I build a 'qx.ui.tree.Tree' and fill in only the
letters (A-Z) as subfolders. Since 5000 is not that many I was initially
populating the entire tree using a nested for-key-in-loop to iterate through
the object. But this was taking long enough that Firefox kept wanting to
stop the script. Any ideas on why it is taking this long - is iterating
through object keys inefficient?
thanks ...
