how to access array inside object without keys

I have a JSON data which look like this:

 {
  "chart":[
     [
        1627776011000,
        28
     ],
     [
        1627776371000,
        38
     ],
     [
        1627776731000,
        48
     ],
     ...
    ]
}

I want to use this data in Chart.js where 1627776011000 ... are x axis values and 28 ... are y axis values.

I know I can do it with an array push

const myArr = JSON.parse(dataJSON);

const data = []; 
const labels = [];

myArr.chart.forEach((item) => {
    labels.push(item[0]);
    data.push(item[1]);
});

but could there be a better way, for example with a map?

>Solution :

You can do it as two calls to map():

const labels = myArr.chart.map(el => el[0]);
const data = myArr.chart.map(el => el[1]);
