The JSON Alex used for demonstration is perfectly fine, in fact it is best practice to have data clearly labeled during development, but for final data output it would be best practiced to have a separate fully compacted copy of the data, this will reduce the .json file size being served for larger arrays.

But for the sake of being thorough for beginners, the array demonstrated in this video can be further simplified as shown below, and it is still 100% valid.

[
    [
        [
            "Alex",
            true
        ],
        [
            "Billy",
            false
        ]
    ]
]

and below is the same data completely compacted.

[[["Alex", true], ["Billy", false]]]

Note that when storing values without key names, square brackets are used instead of curly brackets.

Without assigning key names to each sub-array item, the keys names are now replaced with numeric values determined by their order in the sub-array.
