I am voting to reopen this question as this addresses a problem which is not documented or available in lwc-recipes. I do have an approach here which I would like to add as an answer but cannot add as it's already closed. I am voting to leave closed right now for two reasons which are easily fixable. First, "is not working" needs to be more specific.

I have an LWC page with three section getting data from 3 apex methods all are returning a list of wrapper class, my requirement is lesser initial load time of the page, to fetch data from apex I have two approaches in my mind.

In my case I am sure I won't hit the governor limit if I use 2nd approach but is there any other things to consider and also which approach will take more time to load? Both methods will take approximately the same amount of time to load.

In fact, the "three method" approach may even be faster than using just one method. Unlike Aura, LWC can leverage multiple threads up to six to fetch data from the server.

All things being equal, this means that there will be some performance gain as threads can overlap each other, while Apex cannot execute in parallel in the same thread. If you want faster performance, your only real choice is to figure out a way to either optimize the CPU time or bandwidth used.

This can mean things like making sure you're using efficient loops avoiding nested loopsquerying only the fields and records you need to do your processing, etc. Consolidating your calls into one, at best, will have no appreciable effect, and in some cases, may worsen load times.

The problem is that the promise is not behaving as expected. I expected maybe incorrectly that result in lwcB would be resolved before returning the value to the calling fn lwcA. Can you help me better understand why this isn't working as expected and how I can adjust this code to return a fulfilled promise to the caller?

To start with, I have duplicated the component that we had at the end of using the wire service. And we will start by changing the only HTML change between the two. We are going to change using wire service to using Apex. It declares one static method called initand it has decorated with the aura enabled and is using cachable equals true.

Or we query for the user ID that we get from user info dot get user ID. And if we do find the user, we add that to the return object as the user and then we set the success to true and we return theuser object. You probably need more than this in your own code. Just there you saw me using the autocomplete for that is part of the Visual Studio Code plugins.

And we use init instead of the he getrecord handler. We will pass that into our wire handler. Well, what do we want to do? I like to add a little. There we go. So now when the wire service calls init in our Apex code, the handler is going to.

If nothing goes wrong, and there is data, we set the data dot user onto the this class. We set the user in this class so that we can access it in the template.
