I've now solved this little conundrum and glad to have learned a little more about arrays.
  • There was no need to parse from a JSON file, really I just needed an array of objects, however, I didn't "convert" the JSON properly:
(videoList.json)
{
  "videoList":[
    {
      "name":"Vid One", 
      "index":0, 
      "thumbLink":"assets/vid1.jpg", 
      "playLink": "http://some.tube/video1"
    },
    {
      "name":"Vid Two", 
      "index":1, 
      "thumbLink":"assets/vid2.jpg", 
      "playLink": "https://some.tube/video2"
    }
  ]
}

in js becomes:

(videoList.js)
var videoList = [
    {
      name:"Vid One", 
      index:0, 
      thumbLink:"assets/vid1.jpg", 
      playLink: "http://some.tube/video1"
    },
    {
      name:"Vid Two", 
      index:1, 
      thumbLink:"assets/vid2.jpg", 
      playLink: "https://some.tube/video2"
    }
  ]

(my mistake was that I failed to remove the quotations around "name")
  • in order to get, say, all the "names" into a new array, 'array.map' does the job:
    let names=videoList.map( (item) => item.name);
which gives me a new array containing all the "name" values.

Moving forward, I should be able to do all sorts of useful and interesting things with my youtube videos on my site... At this moment in time, I'd rather maintain a manual list than start wrestling with the YT API!
