Threads in HTML

[javaS_freak]

Hi,
Do we have a concept of threads(as in java) for HTML or JavaScript....as i have to start a graph on a button click and when some other button is clicked i have to clear the graph....so basically i want one thread which keeps executing till some other button is clicked in the main thread
please help
thanks in advance

In short, no. In long, noooooo. If you know Java then it's probably best for you to write an applet in that.
