Importing external JSON file using Native JS

I am working on a personal project where I am trying to import an external JSON array file using native Java Script, do you have any videos in the library which explain the process of reading JSON files. I do not wish to use an external library, the idea is to understand the process.

Thank you Craig

Craig Kempster - Glad to help. But normally, you'd select as "best answer" the answer that contained the information that resolved your issue.   :see_no_evil:

Any comments you might want to make can be added to the question with "add comment" instead of creating another "answer".   :wink:

In the past this would have been a huge pain, but the relatively new native "fetch" function makes this nearly as easy to do as with jQuery:

fetch("array.json")
  .then(response => response.json())
  .then(obj => /* do what you want here with the JSON object "obj" */);

Note that the default security settings of some browsers might not allow loading local files from the computer.

Thank You Steven

Is there a JSON course in Treehouse that you are aware of?

Not that I know of, but there's a Working with the Fetch API workshop.
