I declared a constant, assigned to a fetch. Now, intellisense offers json for that constant.

Is it because vscode knows that fetch can return json?

import topHeadlinesURL from 'newsAPI.js';

// Delay execution until page loads
window.addEventListener('load', ()=> 
 kvetchNews();
);

async function kvetchNews()
 const res = await fetch(topHeadlinesURL);
 const json = await res.json();

  This question doesn't really make sense. The ability to invoke .json on a variable isn't determined by how you declare that variable, var or let or const. It's determined by the value stored therein.

  The picture doesn't add any clarity. It's not clear why you think "constant" is relevant here; as already pointed out, fetch returns something that has a .json method on it, and VSCode knows this because fetch is a built-in standard function; it returns a promise, which you're awaiting, so the resolved value will be a Response object that has a .json method.

  Because there's no useful answer to give here. Intellisense offers .json because it knows .json is something you can invoke on the value stored in res, and its job is to suggest these things to save you time and keystrokes.

  I guess one reason that this question is on hold is because the answer can be considered to not be useful. You believe it is, but sadly those who voted to put the question on hold did not.

A few things; first:

Why Does Intellisense Offer Json for a Constant?

That the variable is a const isn't relevant to the methods the VSCode will suggest. The type of variable doesn't determine what methods can be invoked on it, the value of the variable does. Your variable could be declared var, let or const and it wouldn't change the suggestion of .json.

Second:

This demonstrates a misunderstanding of what VSCode is offering you. Whether or not a method returns JSON is irrelevant (fetch does not), VSCode is suggesting the method json because it knows that the object held by the variable has a json method.

In this case, fetch returns a promise, which resolves to a Response object that has implements the Body mixin, which provides a json method. You're awaiting that promise, so the value stored in the variable with be that response object, on which you can invoke json.

VSCode knows this, because fetch is part of a standard and well documented API: https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API

All VSCode is doing is offering you suggestions for which methods are available for you, saving you the effort of remembering the exact method names and typing them out. Not much of a savings for the four letter json method, but it can be useful for longer methods or for objects that have many methods.
