Read JSON file to a Javascript Array without JQuery

Question

I have a JSON file similar to the following:

[
  "thing1",
  "thing2",
  "thing3",
]

Let's call this file some-things.json.

I have a JavaScript file in the same directory as this JSON. I need the JSON data to be read in as an array, used elsewhere in the JavaScript.

What's the best way to do this? Do I have to read the JSON into a string and then parse to an array, or is there a nicer way? For example, array = ReadJSONArray('some-things.json').

I have looked for duplicates, but I haven't found any questions where the JSON is in a file, not a string.

Also, as stated in the question title, I don't want to use JQuery for this. I have seen a few questions on SO where people have asked this question, but tagged as and/or mentioning JQuery.

read this article, it may help you load the json file in your script: codepen.io/KryptoniteDove/post/… — andrew

For reference, I solved this by using:

var array = require('./some-things.json');

Do I have to read the JSON into a string and then parse to an array…?

In general, yes.

XHR allows you to specify a response type of json, which lets you read the file over XHR and parse it in one go, but support is not universal.
