How to get a group of js function running in background

Question

self.showPanel();
self.updateSliderValue();

self.addPoints(1,2,3);

self.setOptions();
self.removeValues();

addPoints method adds points to app and it takes quite lot of time, so I want it running in background and the app goes to setOptions and other functions below it. Please help.

Answer 1

javascript is a single thread application, that means there is nothing like a background thread to run.

What you can do is run the function addPoints after the main function is completed, you can use setTimeout to do that

setTimeout(function(){
    self.addPoints(1,2,3);
}, 0)

This will defer the execution of addPoints till the current script executions are over.
