Let's say i have the following list in Json and i wish to interchange every value (X,Y) to (Y,X)

[
    [
        [
            99.624023,
            6.249776
        ],
        [
            100.17334,
            5.790897
        ],
        [
            100.50293,
            3.754634
        ],
        [
            100.876465,
            2.833317
        ],
        [
            99.624023,
            6.249776
        ]
    ]
]

Can i ask any simple and better method to solve this case?

`coord[0].forEach(arr => [arr[0], arr[1]] = [arr[1], arr[0]]);` – mplungjan Mar 30 '20 at 09:44
Thanks @mplungjan. And i am looking for optimizing, currently i am using splice method. Looks weird – Wes111222 Mar 30 '20 at 10:24
What optimisation do you expect from the code I posted? – mplungjan Mar 30 '20 at 10:39
Try to make less operation done in JS. Make code structure as easy as possible. I just do like `coord[0].forEach(arr => [arr[1], arr[0]]);` – Wes111222 Mar 30 '20 at 10:45
