LWC: connectedCallback vs. @wire

All,

I am new LWC and documentations have been immensly useful to get me started on this journey. However, while looking at various examples on getting data from objects, i see examples randomly using @wire at someplace and connectedCallback at others. 

question for this group is:
  • what is the basic difference between these 2
  • which situation would call for choosing between these 2 methods
  • @wire does not fire sometime (i mean no calls to the apex method at all)
Thanks,
Navin

Hi Navin,

I found the below article regarding the @wire decorator and connectedCallback().

Can you please have a look at it once.

I hope this helps and in case if this comes handy can you please choose this as best answer so that it can be used by others in the future.
