Deferred versus promise

Question

What is the difference between Deferred and Promise other than the jQuery versions?

What should I use for my need? I only want to call the fooExecute()

Answer 1

A promise is something you can set on a deferred object that executes when the deferred collection is complete.

Example from the jQuery documentation:

  
  



Go
Ready...

Here it is in JSFiddle

This runs a function on each div and executes the .promise code when all .each executions are complete.
