In some cases, the application may require the user to choose a few pages of the PDF.
In such cases PDF. JS is of help.
JS is done asynchronously — from loading the PDF file to loading individual pages to rendering pages. This means that return from such asynchronous operations have to be handled through callbacks.
Now PDF. JS does not use normal callbacks, it uses Promises. Promises and callbacks do almost the same thing, but Promises helps in writing cleaner code.
Instead of writing callbacks such as success or error here and there in your code, you just chain the various callbacks involved by a then for success or catch for error. JS, it returns a Promise variable on each asynchronous operation request.
When the asynchronous operation is completed, the Promise involved receives a parameter in the callback function. Praesent mauris.

Hope that it would help me in creating better and as they say — Kool websites.
Thanks again Geniuzs.
Louis, you chosen writing style was awesome, I just spent 4 days researching jquery, found most of the tutorials totally confusing — then I found yours. Everything fell into place within the few minutes it took to read your tutorial, and a few quick experiments based on your examples worked nicely.
Anyway, many thanks, the article was so helpful and well written. Comment Rules: Please use a real name or alias.In scelerisque sem at dolor. You can also pass binary data as a parameter.
