QUESTION
I want to fetch data from the wikipedia api via node-fetch. Unfortunately I don't manage to set a variable outside my fetch-Promise-Chain. I wanted to pass this variable on to render page to fill in a form. If I consle.log the inside the fetch() everything works as I'd expected.
I am new to this and I admit that I don't understand how promises work or how to get practice on this topic.

When your JS code does an Ajax request over the network to get data from the server, you need to set up the response code in a function (which is also called callback).The JS Engine basiclly tells the hosting environment that he is going to suspend the execution for the moment and when the network response arrives back, please let me know and execute that callback function.
So' in your example, you're making an asynchronous request via fetch. the response will get sometime after you make it but if you won't await that call, the

QUESTION
I'm hoping I can get some help understanding what's happening in this bit of code at a rather fundamental level.
I know that this is basically making a call to the specified URL. I also know that it should be returning a JSON object. If the call succeeds, then it calls my displayResults
function, which I defined below.
The displayResults
function takes a single parameter.
If I pass it a simple string for example ("response", in the code), everything works fine. However, I'd like to pass the response object from the API call as an argument to the function, but I cannot figure out how. Does the response object have a specific name I should be using?

event of the form
element instead and be sure to call preventDefault()
