Question

Ive got a live update twitter thing that i have been trying to build, i notice sometimes it duplicates tweets and goes a little bit nuts. Have i stuffed up somewhere in here?

Thanks in advance
(note i posted something similar before but removed it)

Answer 1

You should define pendingTweets array inside getJSON callback handler because it needs to be initialized to empty array every time you get new tweets.

Working demo

After the first search pendingTweets has all the tweets from this call. Now in the next search you compare and add the add news tweets into this array you should empty it because you are looping through this array and building the markup.
